7# From Paul Eggert (1999-03-22):
8#
9# A good source for time zone historical data outside the U.S. is
10# Thomas G. Shanks, The International Atlas (5th edition),
11# San Diego: ACS Publications, Inc. (1999).
12#
13# Gwillim Law writes that a good source
14# for recent time zone data is the International Air Transport
15# Association's Standard Schedules Information Manual (IATA SSIM),
16# published semiannually.  Law sent in several helpful summaries
17# of the IATA's data after 1990.
18#
19# Except where otherwise noted, Shanks is the source for entries through 1990,
20# and IATA SSIM is the source for entries after 1990.
21#
22# Another source occasionally used is Edward W. Whitman, World Time Differences,
23# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
24# I found in the UCLA library.
25#
26# A reliable and entertaining source about time zones is
27# Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997).
28#
29# I invented the abbreviations marked `*' in the following table;
30# the rest are from earlier versions of this file, or from other sources.

83# Armenia
84# From Paul Eggert (1999-10-29):
85# Shanks has Yerevan switching to 3:00 (with Russian DST) in spring 1991,
86# then to 4:00 with no DST in fall 1995, then readopting Russian DST in 1997.
87# Go with Shanks, even when he disagrees with others.  Edgar Der-Danieliantz
88# <edd@AIC.NET> reported (1996-05-04) that Yerevan probably wouldn't use DST
89# in 1996, though it did use DST in 1995.  IATA SSIM (1991/1998) reports that
90# Armenia switched from 3:00 to 4:00 in 1998 and observed DST after 1991,
91# but started switching at 3:00s in 1998.

170# China
171
172# From Guy Harris:
173# People's Republic of China.  Yes, they really have only one time zone.
174
175# From Bob Devine (1988-01-28):
176# No they don't.  See TIME mag, 1986-02-17 p.52.  Even though
177# China is across 4 physical time zones, before Feb 1, 1986 only the
178# Peking (Bejing) time zone was recognized.  Since that date, China
179# has two of 'em -- Peking's and Urumqi (named after the capital of
180# the Xinjiang Uyghur Autonomous Region).  I don't know about DST for it.
181#
182# . . .I just deleted the DST table and this editor makes it too
183# painful to suck in another copy..  So, here is what I have for
184# DST start/end dates for Peking's time zone (info from AP):
185#
186#     1986 May 4 - Sept 14
187#     1987 mid-April - ??
188
189# From U. S. Naval Observatory (1989-01-19):
190# CHINA               8 H  AHEAD OF UTC  ALL OF CHINA, INCL TAIWAN
191# CHINA               9 H  AHEAD OF UTC  APR 17 - SEP 10
192
193# From Paul Eggert (1995-12-19):
194# Shanks writes that China has had a single time zone since 1980 May 1,
195# observing summer DST from 1986 through 1991; this contradicts Devine's
196# note about Time magazine, though apparently _something_ happened in 1986.
197# Go with Shanks for now.  I made up names for the other pre-1980 time zones.

330# Georgia
331# From Paul Eggert (1994-11-19):
332# Today's _Economist_ (p 60) reports that Georgia moved its clocks forward
333# an hour recently, due to a law proposed by Zurab Murvanidze,
334# an MP who went on a hunger strike for 11 days to force discussion about it!
335# We have no details, but we'll guess they didn't move the clocks back in fall.
336#
337# From Mathew Englander, quoting AP (1996-10-23 13:05-04):
338# Instead of putting back clocks at the end of October, Georgia
339# will stay on daylight savings time this winter to save energy,
340# President Eduard Shevardnadze decreed Wednesday.
341#
342# From the BBC via Joseph S. Myers (2004-06-27):
343#
344# Georgia moved closer to Western Europe on Sunday...  The former Soviet
345# republic has changed its time zone back to that of Moscow.  As a result it
346# is now just four hours ahead of Greenwich Mean Time, rather than five hours
347# ahead.  The switch was decreed by the pro-Western president of Georgia,
348# Mikhail Saakashvili, who said the change was partly prompted by the process
349# of integration into Europe.

364# East Timor
365
366# From Joao Carrascalao, brother of the former governor of East Timor, in
367# <a href="http://etan.org/et99c/december/26-31/30ETMAY.htm">
368# East Timor may be late for its millennium
369# </a> (1999-12-26/31):
370# Portugal tried to change the time forward in 1974 because the sun
371# rises too early but the suggestion raised a lot of problems with the
372# Timorese and I still don't think it would work today because it
373# conflicts with their way of life.
374
375# From Paul Eggert (2000-12-04):
376# We don't have any record of the above attempt.
377# Most likely our records are incomplete, but we have no better data.

380# From Manoel de Almeida e Silva, Deputy Spokesman for the UN Secretary-General
381# (2000-08-16)</a>:
382# The Cabinet of the East Timor Transition Administration decided
383# today to advance East Timor's time by one hour.  The time change,
384# which will be permanent, with no seasonal adjustment, will happen at
385# midnight on Saturday, September 16.

447# Iran
448
449# From Roozbeh Pournader (2003-03-15):
450# This is an English translation of what I just found (originally in Persian).
451# The Gregorian dates in brackets are mine:
452#
453#	Official Newspaper No. 13548-1370/6/25 [1991-09-16]
454#	No. 16760/T233 H				1370/6/10 [1991-09-01]
455#
456#	The Rule About Change of the Official Time of the Country
457#
458#	The Board of Ministers, in the meeting dated 1370/5/23 [1991-08-14],
459#	based on the suggestion number 2221/D dated 1370/4/22 [1991-07-13]
460#	of the Country's Organization for Official and Employment Affairs,
461#	and referring to the law for equating the working hours of workers
462#	and officers in the whole country dated 1359/4/23 [1980-07-14], and
463#	for synchronizing the official times of the country, agreed that:
464#
465#	The official time of the country will should move forward one hour
466#	at the 24[:00] hours of the first day of Farvardin and should return
467#	to its previous state at the 24[:00] hours of the 30th day of
468#	Shahrivar.
469#
470#	First Deputy to the President - Hassan Habibi
471#
472# From personal experience, that agrees with what has been followed
473# for at least the last 5 years.  Before that, for a few years, the
474# date used was the first Thursday night of Farvardin and the last
475# Thursday night of Shahrivar, but I can't give exact dates....
476# I have also changed the abbreviations to what is considered correct
477# here in Iran, IRST for regular time and IRDT for daylight saving time.
478#
479# From Roozbeh Pournader (2005-04-05):
480# The text of the Iranian law, in effect since 1925, clearly mentions
481# that the true solar year is the measure, and there is no arithmetic
482# leap year calculation involved.  There has never been any serious
483# plan to change that law....
484#
485# From Paul Eggert (2005-04-05):
486# Go with Shanks before September 1991, and with Pournader thereafter.
487# I used Ed Reingold's cal-persia in GNU Emacs 21.2 to check Persian dates,
488# stopping after 2037 when 32-bit time_t's overflow.
489# That cal-persia used Birashk's approximation, which disagrees with the solar
490# calendar predictions for the year 2025, so I corrected those dates by hand.
491#
492# From Oscar van Vlijmen (2005-03-30), writing about future
493# discrepancies between cal-persia and the Iranian calendar:
494# For 2091 solar-longitude-after yields 2091-03-20 08:40:07.7 UT for
495# the vernal equinox and that gets so close to 12:00 some local
496# Iranian time that the definition of the correct location needs to be
497# known exactly, amongst other factors.  2157 is even closer:
498# 2157-03-20 08:37:15.5 UT.  But the Gregorian year 2025 should give
499# no interpretation problem whatsoever.  By the way, another instant
500# in the near future where there will be a discrepancy between
501# arithmetical and astronomical Iranian calendars will be in 2058:
502# vernal equinox on 2058-03-20 09:03:05.9 UT.  The Java version of
503# Reingold's/Dershowitz' calculator gives correctly the Gregorian date
504# 2058-03-21 for 1 Farvardin 1437 (astronomical).

565#
566# From Jonathan Lennox (2000-06-12):
567# An article in this week's Economist ("Inside the Saddam-free zone", p. 50 in
568# the U.S. edition) on the Iraqi Kurds contains a paragraph:
569# "The three northern provinces ... switched their clocks this spring and
570# are an hour ahead of Baghdad."
571#
572# But Rives McDow (2000-06-18) quotes a contact in Iraqi-Kurdistan as follows:
573# In the past, some Kurdish nationalists, as a protest to the Iraqi
574# Government, did not adhere to daylight saving time.  They referred
575# to daylight saving as Saddam time.  But, as of today, the time zone
576# in Iraqi-Kurdistan is on standard time with Baghdad, Iraq.
577#
578# So we'll ignore the Economist's claim.

600# Israel
601
602# From Ephraim Silverberg (2001-01-11):
603#
604# I coined "IST/IDT" circa 1988.  Until then there were three
605# different abbreviations in use:
606#
607# JST  Jerusalem Standard Time [Danny Braniss, Hebrew University]
608# IZT  Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
609# EEST Eastern Europe Standard Time [used by almost everyone else]
610#
611# Since timezones should be called by country and not capital cities,
612# I ruled out JST.  As Israel is in Asia Minor and not Eastern Europe,
613# EEST was equally unacceptable.  Since "zonal" was not compatible with
614# any other timezone abbreviation, I felt that 'IST' was the way to go
615# and, indeed, it has received almost universal acceptance in timezone
616# settings in Israeli computers.
617#
618# In any case, I am happy to share timezone abbreviations with India,
619# high on my favorite-country list (and not only because my wife's
620# family is from India).

665# From Ephraim Silverberg
666# (1997-03-04, 1998-03-16, 1998-12-28, 2000-01-17, 2000-07-25, 2004-12-22,
667# and 2005-02-17):
668
669# According to the Office of the Secretary General of the Ministry of
670# Interior, there is NO set rule for Daylight-Savings/Standard time changes.
671# One thing is entrenched in law, however: that there must be at least 150
672# days of daylight savings time annually.  From 1993-1998, the change to
673# daylight savings time was on a Friday morning from midnight IST to
674# 1 a.m IDT; up until 1998, the change back to standard time was on a
675# Saturday night from midnight daylight savings time to 11 p.m. standard
676# time.  1996 is an exception to this rule where the change back to standard
677# time took place on Sunday night instead of Saturday night to avoid
678# conflicts with the Jewish New Year.  In 1999, the change to
679# daylight savings time was still on a Friday morning but from
680# 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
681# was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for
682# 1999 only.  In the year 2000, the change to daylight savings time was
683# similar to 1999, but although the change back will be on a Friday, it
684# will take place from 1 a.m. IDT to midnight IST.  Starting in 2001, all
685# changes to/from will take place at 1 a.m. old time, but now there is no
686# rule as to what day of the week it will take place in as the start date
687# (except in 2003) is the night after the Passover Seder (i.e. the eve
688# of the 16th of Nisan in the lunar Hebrew calendar) and the end date
689# (except in 2002) is three nights before Yom Kippur [Day of Atonement]
690# (the eve of the 7th of Tishrei in the lunar Hebrew calendar).

841# Japan
842
843# `9:00' and `JST' is from Guy Harris.
844
845# From Paul Eggert (1995-03-06):
846# Today's _Asahi Evening News_ (page 4) reports that Japan had
847# daylight saving between 1948 and 1951, but ``the system was discontinued
848# because the public believed it would lead to longer working hours.''
849
850# From Mayumi Negishi in the 2005-08-10 Japan Times
851# <http://www.japantimes.co.jp/cgi-bin/getarticle.pl5?nn20050810f2.htm>:
852# Occupation authorities imposed daylight-saving time on Japan on
853# [1948-05-01]....  But lack of prior debate and the execution of
854# daylight-saving time just three days after the bill was passed generated
855# deep hatred of the concept....  The Diet unceremoniously passed a bill to
856# dump the unpopular system in October 1951, less than a month after the San
857# Francisco Peace Treaty was signed.  (A government poll in 1951 showed 53%
858# of the Japanese wanted to scrap daylight-saving time, as opposed to 30% who
859# wanted to keep it.)
860
861# Shanks writes that daylight saving in Japan during those years was as follows:

867# but the only locations using it (for birth certificates, presumably, since
868# Shanks's audience is astrologers) were US military bases.  For now, assume
869# that for most purposes daylight-saving time was observed; otherwise, what
870# would have been the point of the 1951 poll?
871
872# From Hideyuki Suzuki (1998-11-09):
873# 'Tokyo' usually stands for the former location of Tokyo Astronomical
874# Observatory: E 139 44' 40".90 (9h 18m 58s.727), N 35 39' 16".0.
875# This data is from 'Rika Nenpyou (Chronological Scientific Tables) 1996'
876# edited by National Astronomical Observatory of Japan....
877# JST (Japan Standard Time) has been used since 1888-01-01 00:00 (JST).
878# The law is enacted on 1886-07-07.
879
880# From Hideyuki Suzuki (1998-11-16):
881# The ordinance No. 51 (1886) established "standard time" in Japan,
882# which stands for the time on E 135 degree.
883# In the ordinance No. 167 (1895), "standard time" was renamed to "central
884# standard time".  And the same ordinance also established "western standard
885# time", which stands for the time on E 120 degree....  But "western standard
886# time" was abolished in the ordinance No. 529 (1937).  In the ordinance No.
887# 167, there is no mention regarding for what place western standard time is
888# standard....
889#
890# I wrote "ordinance" above, but I don't know how to translate.
891# In Japanese it's "chokurei", which means ordinance from emperor.
892
893# Shanks claims JST in use since 1896, and that a few places (e.g. Ishigaki)
894# use +0800; go with Suzuki.  Guess that all ordinances took effect on Jan 1.

947# Kazakhstan
948
949# From Paul Eggert (1996-11-22):
950# Andrew Evtichov (1996-04-13) writes that Kazakhstan
951# stayed in sync with Moscow after 1990, and that Aqtobe (formerly Aktyubinsk)
952# and Aqtau (formerly Shevchenko) are the largest cities in their zones.
953# Guess that Aqtau and Aqtobe diverged in 1995, since that's the first time
954# IATA SSIM mentions a third time zone in Kazakhstan.
955
956# From Paul Eggert (2001-10-18):
957# German Iofis, ELSI, Almaty (2001-10-09) reports that Kazakhstan uses
958# RussiaAsia rules, instead of switching at 00:00 as the IATA has it.
959# Go with Shanks, who has them always using RussiaAsia rules.
960# Also go with the following claims of Shanks:
961#
962# - Kazakhstan did not observe DST in 1991.
963# - Qyzylorda switched from +5:00 to +6:00 on 1992-01-19 02:00.
964# - Oral switched from +5:00 to +4:00 in spring 1989.
965
966# <a href="http://www.kazsociety.org.uk/news/2005/03/30.htm">
967# From Kazakhstan Embassy's News Bulletin #11 (2005-03-21):
968# </a>
969# The Government of Kazakhstan passed a resolution March 15 abolishing
970# daylight saving time citing lack of economic benefits and health
971# complications coupled with a decrease in productivity.
972#
973# From Branislav Kojic (in Astana) via Gwillim Law (2005-06-28):
974# ... what happened was that the former Kazakhstan Eastern time zone
975# was "blended" with the Central zone.  Therefore, Kazakhstan now has
976# two time zones, and difference between them is one hour.  The zone
977# closer to UTC is the former Western zone (probably still called the
978# same), encompassing four provinces in the west: Aqtobe, Atyrau,
979# Mangghystau, and West Kazakhstan.  The other zone encompasses
980# everything else....  I guess that would make Kazakhstan time zones
981# de jure UTC+5 and UTC+6 respectively.

1184# "Time: Mongolia has two time zones. Three westernmost provinces of

1190# Mongolia discontinued the use of daylight savings time in 1999; 1998

1194# Some maps in the past have indicated that there was an additional time

1197
1198# From Paul Eggert (1999-12-15):
1199# Naming and spelling is tricky in Mongolia.
1200# We'll use Hovd (also spelled Chovd and Khovd) to represent the west zone;
1201# the capital of the Hovd province is sometimes called Hovd, sometimes Dund-Us,

1203# is good enough for our purposes.

1333# Palestine
1334
1335# From Amos Shapir (1998-02-15):
1336#
1337# From 1917 until 1948-05-15, all of Palestine, including the parts now
1338# known as the Gaza Strip and the West Bank, was under British rule.
1339# Therefore the rules given for Israel for that period, apply there too...
1340#
1341# The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
1342# (except a short occupation by Israel from 1956-11 till 1957-03, but no
1343# time zone was affected then).  It was never formally annexed to Egypt,
1344# though.
1345#
1346# The rest of Palestine was under Jordanian rule at that time, formally
1347# annexed in 1950 as the West Bank (and the word "Trans" was dropped from
1348# the country's previous name of "the Hashemite Kingdom of the
1349# Trans-Jordan").  So the rules for Jordan for that time apply.  Major
1350# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
1351# East Jerusalem.
1352#
1353# Both areas were occupied by Israel in June 1967, but not annexed (except
1354# for East Jerusalem).  They were on Israel time since then; there might
1355# have been a Military Governor's order about time zones, but I'm not aware
1356# of any (such orders may have been issued semi-annually whenever summer
1357# time was in effect, but maybe the legal aspect of time was just neglected).
1358#
1359# The Palestinian Authority was established in 1993, and got hold of most
1360# towns in the West Bank and Gaza by 1995.  I know that in order to
1361# demonstrate...independence, they have been switching to
1362# summer time and back on a different schedule than Israel's, but I don't
1363# know when this was started, or what algorithm is used (most likely the
1364# Jordanian one).
1365#
1366# To summarize, the table should probably look something like that:
1367#
1368# Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-
1369# ------------+-----------+-----------+-----------+-----------
1370# Israel      | Zion      | Zion      | Zion      | Zion
1371# West bank   | Zion      | Jordan    | Zion      | Jordan
1372# Gaza        | Zion      | Egypt     | Zion      | Jordan
1373#
1374# I guess more info may be available from the PA's web page (if/when they
1375# have one).
1376
1377# From Paul Eggert (1998-02-25):
1378# Shanks writes that Gaza did not observe DST until 1957, but we'll go
1379# with Shapir and assume that it observed DST from 1940 through 1947,
1380# and that it used Jordanian rules starting in 1996.
1381# We don't yet need a separate entry for the West Bank, since
1382# the only differences between it and Gaza that we know about
1383# occurred before our cutoff date of 1970.
1384# However, as we get more information, we may need to add entries
1385# for parts of the West Bank as they transitioned from Israel's rules
1386# to Palestine's rules.  If you have more info about this, please
1387# send it to tz@elsie.nci.nih.gov for incorporation into future editions.
1388
1389# From IINS News Service - Israel - 1998-03-23 10:38:07 Israel time,
1390# forwarded by Ephraim Silverberg:
1391#
1392# Despite the fact that Israel changed over to daylight savings time
1393# last week, the PLO Authority (PA) has decided not to turn its clocks
1394# one-hour forward at this time.  As a sign of independence from Israeli rule,
1395# the PA has decided to implement DST in April.
1396
1397# From Paul Eggert (1999-09-20):
1398# Daoud Kuttab writes in
1399# <a href="http://www.jpost.com/com/Archive/22.Apr.1999/Opinion/Article-2.html">
1400# Holiday havoc
1401# </a> (Jerusalem Post, 1999-04-22) that
1402# the Palestinian National Authority changed to DST on 1999-04-15.
1403# I vaguely recall that they switch back in October (sorry, forgot the source).
1404# For now, let's assume that the spring switch was at 24:00,
1405# and that they switch at 0:00 on the 3rd Fridays of April and October.
