11# Unless otherwise specified, the source for data through 1990 is:
12# Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
13# San Diego: ACS Publications, Inc. (2003).
14# Unfortunately this book contains many errors and cites no sources.
15#
16# Gwillim Law writes that a good source
17# for recent time zone data is the International Air Transport
18# Association's Standard Schedules Information Manual (IATA SSIM),
19# published semiannually.  Law sent in several helpful summaries
20# of the IATA's data after 1990.  Except where otherwise noted,
21# IATA SSIM is the source for entries after 1990.

23# Another source occasionally used is Edward W. Whitman, World Time Differences,
24# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
25# I found in the UCLA library.

95# Armenia
96# From Paul Eggert (2006-03-22):
97# Shanks & Pottenger have Yerevan switching to 3:00 (with Russian DST)
98# in spring 1991, then to 4:00 with no DST in fall 1995, then
99# readopting Russian DST in 1997.  Go with Shanks & Pottenger, even
100# when they disagree with others.  Edgar Der-Danieliantz
101# reported (1996-05-04) that Yerevan probably wouldn't use DST
102# in 1996, though it did use DST in 1995.  IATA SSIM (1991/1998) reports that
103# Armenia switched from 3:00 to 4:00 in 1998 and observed DST after 1991,
104# but started switching at 3:00s in 1998.
105
106# From Arthur David Olson (2011-06-15):
107# While Russia abandoned DST in 2011, Armenia may choose to
108# follow Russia's "old" rules.

279# From Bob Devine (1988-01-28):
280# No they don't.  See TIME mag, 1986-02-17 p.52.  Even though
281# China is across 4 physical time zones, before Feb 1, 1986 only the
282# Peking (Beijing) time zone was recognized.  Since that date, China
283# has two of 'em - Peking's and Ürümqi (named after the capital of
284# the Xinjiang Uyghur Autonomous Region).  I don't know about DST for it.
285#
286# . . .I just deleted the DST table and this editor makes it too

331# From Paul Eggert (2014-06-30):
332# Alois Treindl kindly sent me translations of the following two sources:
333#
334# (1)
335# Guo Qingsheng (National Time-Service Center, CAS, Xi'an 710600, China)
336# Beijing Time at the Beginning of the PRC
337# China Historical Materials of Science and Technology
338# (Zhongguo ke ji shi liao, 中国科技史料), Vol. 24, No. 1 (2003)
339# It gives evidence that at the beginning of the PRC, Beijing time was
340# officially apparent solar time!  However, Guo also says that the
341# evidence is dubious, as the relevant institute of astronomy had not
342# been taken over by the PRC yet.  It's plausible that apparent solar
343# time was announced but never implemented, and that people continued
344# to use UT+8.  As the Shanghai radio station (and I presume the
345# observatory) was still under control of French missionaries, it
346# could well have ignored any such mandate.
347#
348# (2)
349# Guo Qing-sheng (Shaanxi Astronomical Observatory, CAS, Xi'an 710600, China)
350# A Study on the Standard Time Changes for the Past 100 Years in China
351# [undated and unknown publication location]
352# It says several things:
353#   * The Qing dynasty used local apparent solar time throughout China.
354#   * The Republic of China instituted Beijing mean solar time effective
355#     the official calendar book of 1914.
356#   * The French Concession in Shanghai set up signal stations in
357#     French docks in the 1890s, controlled by Xujiahui (Zikawei)
358#     Observatory and set to local mean time.
359#   * "From the end of the 19th century" it changed to UT+8.
360#   * Chinese Customs (by then reduced to a tool of foreign powers)
361#     eventually standardized on this time for all ports, and it
362#     became used by railways as well.
363#   * In 1918 the Central Observatory proposed dividing China into
364#     five time zones (see below for details).  This caught on
365#     at first only in coastal areas observing UT+8.
366#   * During WWII all of China was in theory was at UT+7.  In practice
367#     this was ignored in the west, and I presume was ignored in
368#     Japanese-occupied territory.
369#   * Japanese-occupied Manchuria was at UT+9, i.e., Japan time.
370#   * The five-zone plan was resurrected after WWII and officially put into
371#     place (with some modifications) in March 1948.  It's not clear
372#     how well it was observed in areas under Nationalist control.
373#   * The People's Liberation Army used UT+8 during the civil war.
374#
375# An AP article "Shanghai Internat'l Area Little Changed" in the
376# Lewiston (ME) Daily Sun (1939-05-29), p 17, said "Even the time is
377# different - the occupied districts going by Tokyo time, an hour
378# ahead of that prevailing in the rest of Shanghai."  Guess that the
379# Xujiahui Observatory was under French control and stuck with UT+8.
380#
381# In earlier versions of this file, China had many separate Zone entries, but
382# this was based on what were apparently incorrect data in Shanks & Pottenger.
383# This has now been simplified to the two entries Asia/Shanghai and
384# Asia/Urumqi, with the others being links for backward compatibility.
385# Proposed in 1918 and theoretically in effect until 1949 (although in practice
386# mainly observed in coastal areas), the five zones were:
387#
388# Changbai Time ("Long-white Time", Long-white = Heilongjiang area) UT+8.5
389# Asia/Harbin (currently a link to Asia/Shanghai)
390# Heilongjiang (except Mohe county), Jilin

427# From Luther Ma (2009-10-17):
428# Almost all (>99.9%) ethnic Chinese (properly ethnic Han) living in
429# Xinjiang use Chinese Standard Time. Some are aware of Xinjiang time,
430# but have no need of it. All planes, trains, and schools function on
431# what is called "Beijing time." When Han make an appointment in Chinese
432# they implicitly use Beijing time.
433#
434# On the other hand, ethnic Uyghurs, who make up about half the
435# population of Xinjiang, typically use "Xinjiang time" which is two
436# hours behind Beijing time, or UTC +0600. The government of the Xinjiang
437# Uyghur Autonomous Region, (XAUR, or just Xinjiang for short) as well as
438# local governments such as the Ürümqi city government use both times in
439# publications, referring to what is popularly called Xinjiang time as
440# "Ürümqi time." When Uyghurs make an appointment in the Uyghur language
441# they almost invariably use Xinjiang time.
442#
443# (Their ethnic Han compatriots would typically have no clue of its
444# widespread use, however, because so extremely few of them are fluent in
445# Uyghur, comparable to the number of Anglo-Americans fluent in Navajo.)
446#
447# (...As with the rest of China there was a brief interval ending in 1990
448# or 1991 when summer time was in use.  The confusion was severe, with
449# the province not having dual times but four times in use at the same
450# time. Some areas remained on standard Xinjiang time or Beijing time and
451# others moving their clocks ahead.)
452
453# From Luther Ma (2009-11-19):
454# With the risk of being redundant to previous answers these are the most common
455# English "transliterations" (w/o using non-English symbols):
456#
457# 1. Wulumuqi...
458# 2. Kashi...
459# 3. Urumqi...
460# 4. Kashgar...
461# ...
462# 5. It seems that Uyghurs in Ürümqi has been using Xinjiang since at least the
463# 1960's. I know of one Han, now over 50, who grew up in the surrounding
464# countryside and used Xinjiang time as a child.
465#
466# 6. Likewise for Kashgar and the rest of south Xinjiang I don't know of any
467# start date for Xinjiang time.
468#
469# Without having access to local historical records, nor the ability to legally
470# publish them, I would go with October 1, 1949, when Xinjiang became the Uyghur
471# Autonomous Region under the PRC. (Before that Uyghurs, of course, would also
472# not be using Beijing time, but some local time.)
473
474# From David Cochrane (2014-03-26):
475# Just a confirmation that Ürümqi time was implemented in Ürümqi on 1 Feb 1986:
476# http://content.time.com/time/magazine/article/0,9171,960684,00.html
477
478# From Luther Ma (2014-04-22):
479# I have interviewed numerous people of various nationalities and from
480# different localities in Xinjiang and can confirm the information in Guo's
481# report regarding Xinjiang, as well as the Time article reference by David
482# Cochrane.  Whether officially recognized or not (and both are officially
483# recognized), two separate times have been in use in Xinjiang since at least
484# the Cultural Revolution: Xinjiang Time (XJT), aka Ürümqi Time or local time;
485# and Beijing Time.  There is no confusion in Xinjiang as to which name refers
486# to which time. Both are widely used in the province, although in some
487# population groups might be use one to the exclusion of the other.  The only
488# problem is that computers and smart phones list Ürümqi (or Kashgar) as
489# having the same time as Beijing.
490
491# From Paul Eggert (2014-06-30):
492# In the early days of the PRC, Tibet was given its own time zone (UT+6) but
493# this was withdrawn in 1959 and never reinstated; see Tubten Khétsun,
494# Memories of life in Lhasa under Chinese Rule, Columbia U Press, ISBN
495# 978-0231142861 (2008), translator's introduction by Matthew Akester, p x.
496# As this is before our 1970 cutoff, Tibet doesn't need a separate zone.
497#
498# Xinjiang Time is well-documented as being officially recognized.  E.g., see
499# "The Working-Calendar for The Xinjiang Uygur Autonomous Region Government"
500# <http://www.sinkiang.gov.cn/service/ourworking/> (2014-04-22).
501# Unfortunately, we have no good records of time in Xinjiang before 1986.
502# During the 20th century parts of Xinjiang were ruled by the Qing dynasty,
503# the Republic of China, various warlords, the First and Second East Turkestan
504# Republics, the Soviet Union, the Kuomintang, and the People's Republic of
505# China, and tracking down all these organizations' timekeeping rules would be
506# quite a trick.  Approximate this lost history by a transition from LMT to
507# XJT at the start of 1928, the year of accession of the warlord Jin Shuren,
508# which happens to be the date given by Shanks & Pottenger (no doubt as a
509# guess) as the transition from LMT.  Ignore the usage of UT+8 before
510# 1986-02-01 under the theory that the transition date to UT+8 is unknown and
511# that the sort of users who prefer Asia/Urumqi now typically ignored the
512# UT+8 mandate back then.

621# From smallufo (2010-04-03):
622# According to Taiwan's CWB [Central Weather Bureau],
623# http://www.cwb.gov.tw/V6/astronomy/cdata/summert.htm
624# Taipei has DST in 1979 between July 1st and Sep 30.
625
626# From Yu-Cheng Chuang (2013-07-12):
627# On Dec 28, 1895, the Meiji Emperor announced Ordinance No. 167 of
628# Meiji Year 28 "The clause about standard time", mentioned that
629# Taiwan and Penghu Islands, as well as Yaeyama and Miyako Islands
630# (both in Okinawa) adopt the Western Standard Time which is based on
631# 120E. The adoption began from Jan 1, 1896. The original text can be
632# found on Wikisource:
633# http://ja.wikisource.org/wiki/標準時ニ關スル件_(公布時)
634# ... This could be the first adoption of time zone in Taiwan, because
635# during the Qing Dynasty, it seems that there was no time zone
636# declared officially.
637#
638# Later, in the beginning of World War II, on Sep 25, 1937, the Showa
639# Emperor announced Ordinance No. 529 of Showa Year 12 "The clause of
640# revision in the ordinance No. 167 of Meiji year 28 about standard
641# time", in which abolished the adoption of Western Standard Time in
642# western islands (listed above), which means the whole Japan
643# territory, including later occupations, adopt Japan Central Time
644# (UTC+9). The adoption began on Oct 1, 1937. The original text can
645# be found on Wikisource:
646# http://ja.wikisource.org/wiki/明治二十八年勅令第百六十七號標準時ニ關スル件中改正ノ件
647#
648# That is, the time zone of Taipei switched to UTC+9 on Oct 1, 1937.
649
650# From Yu-Cheng Chuang (2014-07-02):
651# I've found more evidence about when the time zone was switched from UTC+9
652# back to UTC+8 after WW2.  I believe it was on Sep 21, 1945.  In a document
653# during Japanese era [1] in which the officer told the staff to change time
654# zone back to Western Standard Time (UTC+8) on Sep 21.  And in another
655# history page of National Cheng Kung University [2], on Sep 21 there is a
656# note "from today, switch back to Western Standard Time".  From these two
657# materials, I believe that the time zone change happened on Sep 21.  And
658# today I have found another monthly journal called "The Astronomical Herald"
659# from The Astronomical Society of Japan [3] in which it mentioned the fact
660# that:
661#
662# 1. Standard Time of the Country (Japan) was adopted on Jan 1, 1888, using
663# the time at 135E (GMT+9)
664#
665# 2. Standard Time of the Country was renamed to Central Standard Time, on Jan
666# 1, 1898, and on the same day, the new territories Taiwan and Penghu islands,
667# as well as Yaeyama and Miyako islands, adopted a new time zone called
668# Western Standard Time, which is in GMT+8.
669#
670# 3. Western Standard Time was deprecated on Sep 30, 1937. From then all the
671# territories of Japan adopted the same time zone, which is Central Standard
672# Time.

681# Yu-Cheng Chuang (2014-07-03):
682# I finally have found the real official gazette about changing back to
683# Western Standard Time on Sep 21 in Taiwan.  It's Taiwan Governor-General
684# Bulletin No. 386 in Showa 20 years (1945), published on Sep 19, 1945. [1] ...
685# [It] abolishes Bulletin No. 207 in Showa 12 years (1937), which is a local
686# bulletin in Taiwan for that Ordinance No. 529. It also mentioned that 1am on
687# Sep 21, 1945 will be 12am on Sep 21.  I think this bulletin is much more
688# official than the one I mentioned in my first mail, because it's from the
689# top-level government in Taiwan. If you're going to quote any resource, this
690# would be a good one.

695# In 1946, DST in Taiwan was from May 15 and ended on Sep 30. The info from

706#
707# Here is a brief translation:
708#
709#   The Summer Time this year is adopted from midnight Apr 15 until Sep 20
710#   midnight. To save (energy?) consumption, we're expanding Summer Time
711#   adoption till Oct 31 midnight.
712#
713# The Central Weather Bureau website didn't mention that, however it can
714# be found from historical government announcement database.
715
716# From Paul Eggert (2014-07-03):
717# As per Yu-Cheng Chuang, say that Taiwan was at UT+9 from 1937-10-01

793# Georgia
794# From Paul Eggert (1994-11-19):
795# Today's _Economist_ (p 60) reports that Georgia moved its clocks forward
796# an hour recently, due to a law proposed by Zurab Murvanidze,
797# an MP who went on a hunger strike for 11 days to force discussion about it!
798# We have no details, but we'll guess they didn't move the clocks back in fall.
799#
800# From Mathew Englander, quoting AP (1996-10-23 13:05-04):
801# Instead of putting back clocks at the end of October, Georgia
802# will stay on daylight savings time this winter to save energy,
803# President Eduard Shevardnadze decreed Wednesday.
804#
805# From the BBC via Joseph S. Myers (2004-06-27):
806#
807# Georgia moved closer to Western Europe on Sunday...  The former Soviet
808# republic has changed its time zone back to that of Moscow.  As a result it
809# is now just four hours ahead of Greenwich Mean Time, rather than five hours
810# ahead.  The switch was decreed by the pro-Western president of Georgia,
811# Mikheil Saakashvili, who said the change was partly prompted by the process
812# of integration into Europe.
813
814# From Teimuraz Abashidze (2005-11-07):
815# Government of Georgia ... decided to NOT CHANGE daylight savings time on
816# [Oct.] 30, as it was done before during last more than 10 years.
817# Currently, we are in fact GMT +4:00, as before 30 October it was GMT
818# +3:00.... The problem is, there is NO FORMAL LAW or governmental document
819# about it.  As far as I can find, I was told, that there is no document,
820# because we just DIDN'T ISSUE document about switching to winter time....
821# I don't know what can be done, especially knowing that some years ago our
822# DST rules where changed THREE TIMES during one month.

846# From João Carrascalão, brother of the former governor of East Timor, in
847# East Timor may be late for its millennium
848# <http://etan.org/et99c/december/26-31/30ETMAY.htm> (1999-12-26/31):
849# Portugal tried to change the time forward in 1974 because the sun
850# rises too early but the suggestion raised a lot of problems with the
851# Timorese and I still don't think it would work today because it
852# conflicts with their way of life.
853
854# From Paul Eggert (2000-12-04):
855# We don't have any record of the above attempt.
856# Most likely our records are incomplete, but we have no better data.

858# From Manoel de Almeida e Silva, Deputy Spokesman for the UN Secretary-General
859# http://www.hri.org/news/world/undh/2000/00-08-16.undh.html
860# (2000-08-16):
861# The Cabinet of the East Timor Transition Administration decided
862# today to advance East Timor's time by one hour.  The time change,
863# which will be permanent, with no seasonal adjustment, will happen at

891# civil time was 7:07:12.5; round to even for Jakarta.
892#
893# From Gwillim Law (2001-05-28), overriding Shanks & Pottenger:
894# http://www.sumatera-inc.com/go_to_invest/about_indonesia.asp#standtime
895# says that Indonesia's time zones changed on 1988-01-01.  Looking at some
896# time zone maps, I think that must refer to Western Borneo (Kalimantan Barat
897# and Kalimantan Tengah) switching from UTC+8 to UTC+7.
898#
899# From Paul Eggert (2007-03-10):
900# Here is another correction to Shanks & Pottenger.
901# JohnTWB writes that Japanese forces did not surrender control in
902# Indonesia until 1945-09-01 00:00 at the earliest (in Jakarta) and
903# other formal surrender ceremonies were September 9, 11, and 13, plus
904# September 12 for the regional surrender to Mountbatten in Singapore.
905# These would be the earliest possible times for a change.
906# Régimes horaires pour le monde entier, by Henri Le Corre, (Éditions
907# Traditionnelles, 1987, Paris) says that Java and Madura switched
908# from JST to UTC+07:30 on 1945-09-23, and gives 1944-09-01 for Jayapura
909# (Hollandia).  For now, assume all Indonesian locations other than Jayapura
910# switched on 1945-09-23.
911#
912# From Paul Eggert (2013-08-11):
913# Normally the tz database uses English-language abbreviations, but in
914# Indonesia it's typical to use Indonesian-language abbreviations even
915# when writing in English.  For example, see the English-language
916# summary published by the Time and Frequency Laboratory of the
917# Research Center for Calibration, Instrumentation and Metrology,
918# Indonesia, <http://time.kim.lipi.go.id/time-eng.php> (2006-09-29).

962# From Roozbeh Pournader (2003-03-15):
963# This is an English translation of what I just found (originally in Persian).
964# The Gregorian dates in brackets are mine:
965#
966#	Official Newspaper No. 13548-1370/6/25 [1991-09-16]
967#	No. 16760/T233 H				1370/6/10 [1991-09-01]
968#
969#	The Rule About Change of the Official Time of the Country
970#
971#	The Board of Ministers, in the meeting dated 1370/5/23 [1991-08-14],
972#	based on the suggestion number 2221/D dated 1370/4/22 [1991-07-13]
973#	of the Country's Organization for Official and Employment Affairs,
974#	and referring to the law for equating the working hours of workers
975#	and officers in the whole country dated 1359/4/23 [1980-07-14], and
976#	for synchronizing the official times of the country, agreed that:
977#
978#	The official time of the country will should move forward one hour
979#	at the 24[:00] hours of the first day of Farvardin and should return
980#	to its previous state at the 24[:00] hours of the 30th day of
981#	Shahrivar.
982#
983#	First Deputy to the President - Hassan Habibi
984#
985# From personal experience, that agrees with what has been followed
986# for at least the last 5 years.  Before that, for a few years, the
987# date used was the first Thursday night of Farvardin and the last
988# Thursday night of Shahrivar, but I can't give exact dates....
989# I have also changed the abbreviations to what is considered correct
990# here in Iran, IRST for regular time and IRDT for daylight saving time.
991#
992# From Roozbeh Pournader (2005-04-05):
993# The text of the Iranian law, in effect since 1925, clearly mentions
994# that the true solar year is the measure, and there is no arithmetic
995# leap year calculation involved.  There has never been any serious
996# plan to change that law....
997#
998# From Paul Eggert (2006-03-22):
999# Go with Shanks & Pottenger before Sept. 1991, and with Pournader thereafter.
1000# I used Ed Reingold's cal-persia in GNU Emacs 21.2 to check Persian dates,
1001# stopping after 2037 when 32-bit time_t's overflow.
1002# That cal-persia used Birashk's approximation, which disagrees with the solar
1003# calendar predictions for the year 2025, so I corrected those dates by hand.
1004#
1005# From Oscar van Vlijmen (2005-03-30), writing about future
1006# discrepancies between cal-persia and the Iranian calendar:
1007# For 2091 solar-longitude-after yields 2091-03-20 08:40:07.7 UT for
1008# the vernal equinox and that gets so close to 12:00 some local
1009# Iranian time that the definition of the correct location needs to be
1010# known exactly, amongst other factors.  2157 is even closer:
1011# 2157-03-20 08:37:15.5 UT.  But the Gregorian year 2025 should give
1012# no interpretation problem whatsoever.  By the way, another instant
1013# in the near future where there will be a discrepancy between
1014# arithmetical and astronomical Iranian calendars will be in 2058:
1015# vernal equinox on 2058-03-20 09:03:05.9 UT.  The Java version of
1016# Reingold's/Dershowitz' calculator gives correctly the Gregorian date
1017# 2058-03-21 for 1 Farvardin 1437 (astronomical).
1018#
1019# From Steffen Thorsen (2006-03-22):
1020# Several of my users have reported that Iran will not observe DST anymore:
1021# http://www.irna.ir/en/news/view/line-17/0603193812164948.htm
1022#
1023# From Reuters (2007-09-16), with a heads-up from Jesper Nørgaard Welen:
1024# ... the Guardian Council ... approved a law on Sunday to re-introduce
1025# daylight saving time ...
1026# http://uk.reuters.com/article/oilRpt/idUKBLA65048420070916
1027#
1028# From Roozbeh Pournader (2007-11-05):
1029# This is quoted from Official Gazette of the Islamic Republic of
1030# Iran, Volume 63, Number 18242, dated Tuesday 1386/6/24
1031# [2007-10-16]. I am doing the best translation I can:...
1032# The official time of the country will be moved forward for one hour

1097# From Jonathan Lennox (2000-06-12):
1098# An article in this week's Economist ("Inside the Saddam-free zone", p. 50 in
1099# the U.S. edition) on the Iraqi Kurds contains a paragraph:
1100# "The three northern provinces ... switched their clocks this spring and
1101# are an hour ahead of Baghdad."
1102#
1103# But Rives McDow (2000-06-18) quotes a contact in Iraqi-Kurdistan as follows:
1104# In the past, some Kurdish nationalists, as a protest to the Iraqi
1105# Government, did not adhere to daylight saving time.  They referred
1106# to daylight saving as Saddam time.  But, as of today, the time zone
1107# in Iraqi-Kurdistan is on standard time with Baghdad, Iraq.
1108#
1109# So we'll ignore the Economist's claim.

1143# From Ephraim Silverberg (2001-01-11):
1144#
1145# I coined "IST/IDT" circa 1988.  Until then there were three
1146# different abbreviations in use:
1147#
1148# JST  Jerusalem Standard Time [Danny Braniss, Hebrew University]
1149# IZT  Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
1150# EEST Eastern Europe Standard Time [used by almost everyone else]
1151#
1152# Since timezones should be called by country and not capital cities,
1153# I ruled out JST.  As Israel is in Asia Minor and not Eastern Europe,
1154# EEST was equally unacceptable.  Since "zonal" was not compatible with
1155# any other timezone abbreviation, I felt that 'IST' was the way to go
1156# and, indeed, it has received almost universal acceptance in timezone
1157# settings in Israeli computers.
1158#
1159# In any case, I am happy to share timezone abbreviations with India,
1160# high on my favorite-country list (and not only because my wife's
1161# family is from India).

1211# From Ephraim Silverberg
1212# (1997-03-04, 1998-03-16, 1998-12-28, 2000-01-17, 2000-07-25, 2004-12-22,
1213# and 2005-02-17):
1214
1215# According to the Office of the Secretary General of the Ministry of
1216# Interior, there is NO set rule for Daylight-Savings/Standard time changes.
1217# One thing is entrenched in law, however: that there must be at least 150
1218# days of daylight savings time annually.  From 1993-1998, the change to
1219# daylight savings time was on a Friday morning from midnight IST to
1220# 1 a.m IDT; up until 1998, the change back to standard time was on a
1221# Saturday night from midnight daylight savings time to 11 p.m. standard
1222# time.  1996 is an exception to this rule where the change back to standard
1223# time took place on Sunday night instead of Saturday night to avoid
1224# conflicts with the Jewish New Year.  In 1999, the change to
1225# daylight savings time was still on a Friday morning but from
1226# 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
1227# was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for
1228# 1999 only.  In the year 2000, the change to daylight savings time was
1229# similar to 1999, but although the change back will be on a Friday, it
1230# will take place from 1 a.m. IDT to midnight IST.  Starting in 2001, all
1231# changes to/from will take place at 1 a.m. old time, but now there is no
1232# rule as to what day of the week it will take place in as the start date
1233# (except in 2003) is the night after the Passover Seder (i.e. the eve
1234# of the 16th of Nisan in the lunar Hebrew calendar) and the end date
1235# (except in 2002) is three nights before Yom Kippur [Day of Atonement]
1236# (the eve of the 7th of Tishrei in the lunar Hebrew calendar).

1411# The ordinance No. 51 (1886) established "standard time" in Japan,

1413# In the ordinance No. 167 (1895), "standard time" was renamed to "central
1414# standard time".  And the same ordinance also established "western standard
1415# time", which stands for the time on 120 degrees E....  But "western standard
1416# time" was abolished in the ordinance No. 529 (1937).  In the ordinance No.

1542
1543# From Paul Eggert (1996-11-22):
1544# Andrew Evtichov (1996-04-13) writes that Kazakhstan
1545# stayed in sync with Moscow after 1990, and that Aqtobe (formerly Aktyubinsk)
1546# and Aqtau (formerly Shevchenko) are the largest cities in their zones.
1547# Guess that Aqtau and Aqtobe diverged in 1995, since that's the first time
1548# IATA SSIM mentions a third time zone in Kazakhstan.
1549
1550# From Paul Eggert (2006-03-22):
1551# German Iofis, ELSI, Almaty (2001-10-09) reports that Kazakhstan uses
1552# RussiaAsia rules, instead of switching at 00:00 as the IATA has it.
1553# Go with Shanks & Pottenger, who have them always using RussiaAsia rules.
1554# Also go with the following claims of Shanks & Pottenger:
1555#
1556# - Kazakhstan did not observe DST in 1991.
1557# - Qyzylorda switched from +5:00 to +6:00 on 1992-01-19 02:00.
1558# - Oral switched from +5:00 to +4:00 in spring 1989.
1559
1560# From Kazakhstan Embassy's News Bulletin #11
1561# <http://www.kazsociety.org.uk/news/2005/03/30.htm> (2005-03-21):
1562# The Government of Kazakhstan passed a resolution March 15 abolishing
1563# daylight saving time citing lack of economic benefits and health
1564# complications coupled with a decrease in productivity.
1565#
1566# From Branislav Kojic (in Astana) via Gwillim Law (2005-06-28):
1567# ... what happened was that the former Kazakhstan Eastern time zone
1568# was "blended" with the Central zone.  Therefore, Kazakhstan now has
1569# two time zones, and difference between them is one hour.  The zone
1570# closer to UTC is the former Western zone (probably still called the
1571# same), encompassing four provinces in the west: Aqtobe, Atyrau,
1572# Mangghystau, and West Kazakhstan.  The other zone encompasses
1573# everything else....  I guess that would make Kazakhstan time zones
1574# de jure UTC+5 and UTC+6 respectively.

1808
1809# From Oscar van Vlijmen (1999-12-11):
1810# General Information Mongolia
1811# <http://www.mongoliatourism.gov.mn/general.htm> (1999-09)
1812# "Time: Mongolia has two time zones. Three westernmost provinces of
1813# Bayan-Ölgii, Uvs, and Hovd are one hour earlier than the capital city, and
1814# the rest of the country follows the Ulaanbaatar time, which is UTC/GMT plus
1815# eight hours."
1816
1817# From Rives McDow (1999-12-13):
1818# Mongolia discontinued the use of daylight savings time in 1999; 1998
1819# being the last year it was implemented.  The dates of implementation I am
1820# unsure of, but most probably it was similar to Russia, except for the time
1821# of implementation may have been different....
1822# Some maps in the past have indicated that there was an additional time
1823# zone in the eastern part of Mongolia, including the provinces of Dornod,
1824# Sükhbaatar, and possibly Khentii.
1825
1826# From Paul Eggert (1999-12-15):
1827# Naming and spelling is tricky in Mongolia.
1828# We'll use Hovd (also spelled Chovd and Khovd) to represent the west zone;
1829# the capital of the Hovd province is sometimes called Hovd, sometimes Dund-Us,
1830# and sometimes Jirgalanta (with variant spellings), but the name Hovd
1831# is good enough for our purposes.
1832
1833# From Rives McDow (2001-05-13):
1834# In addition to Mongolia starting daylight savings as reported earlier
1835# (adopted DST on 2001-04-27 02:00 local time, ending 2001-09-28),
1836# there are three time zones.

1842#
1843# [The province of Selenge is omitted from the above lists.]
1844
1845# From Ganbold Ts., Ulaanbaatar (2004-04-17):
1846# Daylight saving occurs at 02:00 local time last Saturday of March.
1847# It will change back to normal at 02:00 local time last Saturday of
1848# September.... As I remember this rule was changed in 2001.

1853

1855# We have wildly conflicting information about Mongolia's time zones.
1856# Bill Bonnet (2005-05-19) reports that the US Embassy in Ulaanbaatar says
1857# there is only one time zone and that DST is observed, citing Microsoft
1858# Windows XP as the source.  Risto Nykänen (2005-05-16) reports that
1859# travelmongolia.org says there are two time zones (UTC+7, UTC+8) with no DST.
1860# Oscar van Vlijmen (2005-05-20) reports that the Mongolian Embassy in
1861# Washington, DC says there are two time zones, with DST observed.

1863# http://ubpost.mongolnews.mn/index.php?subaction=showcomments&id=1111634894&archive=&start_from=&ucat=1&
1864# which also says that there is DST, and which has a comment by "Toddius"
1865# (2005-03-31 06:05 +0700) saying "Mongolia actually has 3.5 time zones.
1866# The West (OLGII) is +7 GMT, most of the country is ULAT is +8 GMT

1893#
1894# There it appears that flights between Choibalsan and Ulaanbaatar arrive
1895# about 1:35 - 1:50 hours later in local clock time, no matter the
1896# direction, while Ulaanbaatar-Khovd takes 2 hours in the Eastern
1897# direction and 3:35 back, which indicates that Ulaanbaatar and Khovd are
1898# in different time zones (like we know about), while Choibalsan and
1899# Ulaanbaatar are in the same time zone (correction needed).
1900
1901# From Arthur David Olson (2008-05-19):
1902# Assume that Choibalsan is indeed offset by 8:00.
1903# XXX--in the absence of better information, assume that transition
1904# was at the start of 2008-03-31 (the day of Steffen Thorsen's report);
1905# this is almost surely wrong.
1906
1907# From Ganbold Tsagaankhuu (2015-03-10):

1976# advance the clocks by one hour on the night between the first

1978# 15th October each year".  This agrees with McDow's 04-07 at 00:00,
1979# but disagrees about the October transition, and makes it sound like
1980# it's not on a trial basis.  Also, the "between the first Saturday

2113# Palestine
2114
2115# From Amos Shapir (1998-02-15):
2116#
2117# From 1917 until 1948-05-15, all of Palestine, including the parts now
2118# known as the Gaza Strip and the West Bank, was under British rule.
2119# Therefore the rules given for Israel for that period, apply there too...
2120#
2121# The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
2122# (except a short occupation by Israel from 1956-11 till 1957-03, but no
2123# time zone was affected then).  It was never formally annexed to Egypt,
2124# though.
2125#
2126# The rest of Palestine was under Jordanian rule at that time, formally
2127# annexed in 1950 as the West Bank (and the word "Trans" was dropped from
2128# the country's previous name of "the Hashemite Kingdom of the
2129# Trans-Jordan").  So the rules for Jordan for that time apply.  Major
2130# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
2131# East Jerusalem.
2132#
2133# Both areas were occupied by Israel in June 1967, but not annexed (except
2134# for East Jerusalem).  They were on Israel time since then; there might
2135# have been a Military Governor's order about time zones, but I'm not aware
2136# of any (such orders may have been issued semi-annually whenever summer
2137# time was in effect, but maybe the legal aspect of time was just neglected).
2138#
2139# The Palestinian Authority was established in 1993, and got hold of most
2140# towns in the West Bank and Gaza by 1995.  I know that in order to
2141# demonstrate...independence, they have been switching to
2142# summer time and back on a different schedule than Israel's, but I don't
2143# know when this was started, or what algorithm is used (most likely the
2144# Jordanian one).
2145#
2146# To summarize, the table should probably look something like that:
2147#
2148# Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-
2149# ------------+-----------+-----------+-----------+-----------
2150# Israel      | Zion      | Zion      | Zion      | Zion
2151# West bank   | Zion      | Jordan    | Zion      | Jordan
2152# Gaza        | Zion      | Egypt     | Zion      | Jordan
2153#
2154# I guess more info may be available from the PA's web page (if/when they
2155# have one).
2156
2157# From Paul Eggert (2006-03-22):
2158# Shanks & Pottenger write that Gaza did not observe DST until 1957, but go
2159# with Shapir and assume that it observed DST from 1940 through 1947,
2160# and that it used Jordanian rules starting in 1996.
2161# We don't yet need a separate entry for the West Bank, since
2162# the only differences between it and Gaza that we know about
2163# occurred before our cutoff date of 1970.
2164# However, as we get more information, we may need to add entries
2165# for parts of the West Bank as they transitioned from Israel's rules
2166# to Palestine's rules.
2167
2168# From IINS News Service - Israel - 1998-03-23 10:38:07 Israel time,
2169# forwarded by Ephraim Silverberg:
2170#
2171# Despite the fact that Israel changed over to daylight savings time
2172# last week, the PLO Authority (PA) has decided not to turn its clocks
2173# one-hour forward at this time.  As a sign of independence from Israeli rule,
2174# the PA has decided to implement DST in April.
2175
2176# From Paul Eggert (1999-09-20):
2177# Daoud Kuttab writes in Holiday havoc
2178# http://www.jpost.com/com/Archive/22.Apr.1999/Opinion/Article-2.html
2179# (Jerusalem Post, 1999-04-22) that
2180# the Palestinian National Authority changed to DST on 1999-04-15.
2181# I vaguely recall that they switch back in October (sorry, forgot the source).
2182# For now, let's assume that the spring switch was at 24:00,
2183# and that they switch at 0:00 on the 3rd Fridays of April and October.
2184
2185# From Paul Eggert (2005-11-22):
2186# Starting 2004 transitions are from Steffen Thorsen's web site timeanddate.com.
2187
2188# From Steffen Thorsen (2005-11-23):
2189# A user from Gaza reported that Gaza made the change early because of
2190# the Ramadan.  Next year Ramadan will be even earlier, so I think
2191# there is a good chance next year's end date will be around two weeks
2192# earlier - the same goes for Jordan.
2193
2194# From Steffen Thorsen (2006-08-17):
2195# I was informed by a user in Bethlehem that in Bethlehem it started the
2196# same day as Israel, and after checking with other users in the area, I
2197# was informed that they started DST one day after Israel.  I was not
2198# able to find any authoritative sources at the time, nor details if
2199# Gaza changed as well, but presumed Gaza to follow the same rules as
2200# the West Bank.
2201
2202# From Steffen Thorsen (2006-09-26):

2208# I guess it is likely that next year's date will be moved as well,
2209# because of the Ramadan.
2210
2211# From Jesper Nørgaard Welen (2007-09-18):
2212# According to Steffen Thorsen's web site the Gaza Strip and the rest of the
2213# Palestinian territories left DST early on 13.th. of September at 2:00.
2214
2215# From Paul Eggert (2007-09-20):
2216# My understanding is that Gaza and the West Bank disagree even over when
2217# the weekend is (Thursday+Friday versus Friday+Saturday), so I'd be a bit
2218# surprised if they agreed about DST.  But for now, assume they agree.
2219# For lack of better information, predict that future changes will be
2220# the 2nd Thursday of September at 02:00.

2467# From Paul Eggert (2014-07-15):
2468# Time in Saudi Arabia and other countries in the Arabian peninsula was not
2469# standardized until relatively recently; we don't know when, and possibly it
2470# has never been made official.  Richard P Hunt, in "Islam city yielding to
2471# modern times", New York Times (1961-04-09), p 20, wrote that only airlines
2472# observed standard time, and that people in Jeddah mostly observed quasi-solar
2473# time, doing so by setting their watches at sunrise to 6 o'clock (or to 12
2474# o'clock for "Arab" time).
2475#
2476# The TZ database cannot represent quasi-solar time; airline time is the best
2477# we can do.  The 1946 foreign air news digest of the U.S. Civil Aeronautics
2478# Board (OCLC 42299995) reported that the "... Arabian Government, inaugurated
2479# a weekly Dhahran-Cairo service, via the Saudi Arabian cities of Riyadh and
2480# Jidda, on March 14, 1947".  Shanks & Pottenger guessed 1950; go with the
2481# earlier date.
2482#
2483# Shanks & Pottenger also state that until 1968-05-01 Saudi Arabia had two
2484# time zones; the other zone, at UTC+4, was in the far eastern part of
2485# the country.  Ignore this, as it's before our 1970 cutoff.

2539# [The Tamil Tigers] never accepted the original 1996 time change and simply

2542# From Paul Eggert (2006-04-18):
2543# People who live in regions under Tamil control can use [TZ='Asia/Kolkata'],
2544# as that zone has agreed with the Tamil areas since our cutoff date of 1970.
2545
2546# From K Sethu (2006-04-25):
2547# I think the abbreviation LKT originated from the world of computers at
2548# the time of or subsequent to the time zone changes by SL Government
2549# twice in 1996 and probably SL Government or its standardization
2550# agencies never declared an abbreviation as a national standard.
2551#
2552# I recollect before the recent change the government announcements
2553# mentioning it as simply changing Sri Lanka Standard Time or Sri Lanka
2554# Time and no mention was made about the abbreviation.
2555#
2556# If we look at Sri Lanka Department of Government's "Official News
2557# Website of Sri Lanka" ... http://www.news.lk/ we can see that they
2558# use SLT as abbreviation in time stamp at the beginning of each news
2559# item....
2560#
2561# Within Sri Lanka I think LKT is well known among computer users and
2562# administrators.  In my opinion SLT may not be a good choice because the
2563# nation's largest telcom / internet operator Sri Lanka Telcom is well
2564# known by that abbreviation - simply as SLT (there IP domains are
2565# slt.lk and sltnet.lk).
2566#
2567# But if indeed our government has adopted SLT as standard abbreviation
2568# (that we have not known so far) then  it is better that it be used for
2569# all computers.
2570
2571# From Paul Eggert (2006-04-25):
2572# One possibility is that we wait for a bit for the dust to settle down

2803# From Paul Eggert (2014-10-04):
2804# Milne gives 7:16:56 for the meridian of Saigon in 1899, as being
2805# used in Lower Laos, Cambodia, and Annam.  But this is quite a ways
2806# from Saigon's location.  For now, ignore this and stick with Shanks
2807# and Pottenger for LMT before 1906.
2808
2809# From Arthur David Olson (2008-03-18):
2810# The English-language name of Vietnam's most populous city is "Ho Chi Minh
2811# City"; use Ho_Chi_Minh below to avoid a name of more than 14 characters.
2812
2813# From Paul Eggert (2014-10-21) after a heads-up from Trần Ngọc Quân:
2814# Trần Tiến Bình's authoritative book "Lịch Việt Nam: thế kỷ XX-XXI (1901-2100)"
2815# (Nhà xuất bản Văn Hoá - Thông Tin, Hanoi, 2005), pp 49-50,
2816# is quoted verbatim in:
2817# http://www.thoigian.com.vn/?mPage=P80D01
2818# is translated by Brian Inglis in:
2819# http://mm.icann.org/pipermail/tz/2014-October/021654.html
2820# and is the basis for the information below.
2821#
2822# The 1906 transition was effective July 1 and standardized Indochina to
2823# Phù Liễn Observatory, legally 104 deg. 17'17" east of Paris.
2824# It's unclear whether this meant legal Paris Mean Time (00:09:21) or
2825# the Paris Meridian (2 deg. 20'14.03" E); the former yields 07:06:30.1333...
2826# and the latter 07:06:29.333... so either way it rounds to 07:06:30,
2827# which is used below even though the modern-day Phù Liễn Observatory
2828# is closer to 07:06:31.  Abbreviate Phù Liễn Mean Time as PLMT.
2829#
2830# The following transitions occurred in Indochina in general (before 1954)
2831# and in South Vietnam in particular (after 1954):
2832# To 07:00 on 1911-05-01.
2833# To 08:00 on 1942-12-31 at 23:00.
2834# To 09:00 in 1945-03-14 at 23:00.
2835# To 07:00 on 1945-09-02 in Vietnam.
2836# To 08:00 on 1947-04-01 in French-controlled Indochina.
2837# To 07:00 on 1955-07-01 in South Vietnam.
2838# To 08:00 on 1959-12-31 at 23:00 in South Vietnam.
2839# To 07:00 on 1975-06-13 in South Vietnam.
