10# From Paul Eggert (2006-03-22):
11#
12# A good source for time zone historical data outside the U.S. is
13# Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
14# San Diego: ACS Publications, Inc. (2003).
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.
21#
22# Except where otherwise noted, Shanks & Pottenger is the source for
23# entries through 1990, and IATA SSIM is the source for entries afterwards.
24#
25# Another source occasionally used is Edward W. Whitman, World Time Differences,
26# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
27# I found in the UCLA library.
28#
29# A reliable and entertaining source about time zones is
30# Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997).
31#
32# I invented the abbreviations marked `*' in the following table;
33# the rest are from earlier versions of this file, or from other sources.

88# From Paul Eggert (2006-03-22):
89# Shanks & Pottenger have Yerevan switching to 3:00 (with Russian DST)

91# readopting Russian DST in 1997.  Go with Shanks & Pottenger, even

93# reported (1996-05-04) that Yerevan probably wouldn't use DST
94# in 1996, though it did use DST in 1995.  IATA SSIM (1991/1998) reports that
95# Armenia switched from 3:00 to 4:00 in 1998 and observed DST after 1991,

284# From Guy Harris:
285# People's Republic of China.  Yes, they really have only one time zone.
286
287# From Bob Devine (1988-01-28):
288# No they don't.  See TIME mag, 1986-02-17 p.52.  Even though
289# China is across 4 physical time zones, before Feb 1, 1986 only the
290# Peking (Bejing) time zone was recognized.  Since that date, China
291# has two of 'em -- Peking's and Urumqi (named after the capital of
292# the Xinjiang Uyghur Autonomous Region).  I don't know about DST for it.
293#
294# . . .I just deleted the DST table and this editor makes it too
295# painful to suck in another copy..  So, here is what I have for
296# DST start/end dates for Peking's time zone (info from AP):
297#
298#     1986 May 4 - Sept 14
299#     1987 mid-April - ??

323# BTW, I did some research on-line and found some info regarding these five
324# historic timezones from some Taiwan websites.  And yes, there are official
325# Chinese names for these locales (before 1949).
326#
327# From Jesper Norgaard Welen (2006-07-14):
328# I have investigated the timezones around 1970 on the
329# http://www.astro.com/atlas site [with provinces and county
330# boundaries summarized below]....  A few other exceptions were two
331# counties on the Sichuan side of the Xizang-Sichuan border,
332# counties Dege and Baiyu which lies on the Sichuan side and are
333# therefore supposed to be GMT+7, Xizang region being GMT+6, but Dege
334# county is GMT+8 according to astro.com while Baiyu county is GMT+6
335# (could be true), for the moment I am assuming that those two
336# counties are mistakes in the astro.com data.
337
338# From Paul Eggert (2008-02-11):
339# I just now checked Google News for western news sources that talk
340# about China's single time zone, and couldn't find anything before 1986
341# talking about China being in one time zone.  (That article was: Jim
342# Mann, "A clumsy embrace for another western custom: China on daylight
343# time--sort of", Los Angeles Times, 1986-05-05.  By the way, this
344# article confirms the tz database's data claiming that China began
345# observing daylight saving time in 1986.
346#
347# From Thomas S. Mullaney (2008-02-11):
348# I think you're combining two subjects that need to treated
349# separately: daylight savings (which, you're correct, wasn't
350# implemented until the 1980s) and the unified time zone centered near
351# Beijing (which was implemented in 1949). Briefly, there was also a
352# "Lhasa Time" in Tibet and "Urumqi Time" in Xinjiang. The first was
353# ceased, and the second eventually recognized (again, in the 1980s).
354#
355# From Paul Eggert (2008-06-30):
356# There seems to be a good chance China switched to a single time zone in 1949
357# rather than in 1980 as Shanks & Pottenger have it, but we don't have a
358# reliable documentary source saying so yet, so for now we still go with

401# From Luther Ma (2009-10-17):
402# Almost all (>99.9%) ethnic Chinese (properly ethnic Han) living in
403# Xinjiang use Chinese Standard Time. Some are aware of Xinjiang time,
404# but have no need of it. All planes, trains, and schools function on
405# what is called "Beijing time." When Han make an appointment in Chinese
406# they implicitly use Beijing time.
407#
408# On the other hand, ethnic Uyghurs, who make up about half the
409# population of Xinjiang, typically use "Xinjiang time" which is two
410# hours behind Beijing time, or UTC +0600. The government of the Xinjiang
411# Uyghur Autonomous Region, (XAUR, or just Xinjiang for short) as well as
412# local governments such as the Urumqi city government use both times in
413# publications, referring to what is popularly called Xinjiang time as
414# "Urumqi time." When Uyghurs make an appointment in the Uyghur language
415# they almost invariably use Xinjiang time.
416#
417# (Their ethnic Han compatriots would typically have no clue of its
418# widespread use, however, because so extremely few of them are fluent in
419# Uyghur, comparable to the number of Anglo-Americans fluent in Navajo.)
420#
421# (...As with the rest of China there was a brief interval ending in 1990
422# or 1991 when summer time was in use.  The confusion was severe, with
423# the province not having dual times but four times in use at the same
424# time. Some areas remained on standard Xinjiang time or Beijing time and
425# others moving their clocks ahead.)

442# From Luther Ma (2009-11-19):
443# With the risk of being redundant to previous answers these are the most common
444# English "transliterations" (w/o using non-English symbols):
445#
446# 1. Wulumuqi...
447# 2. Kashi...
448# 3. Urumqi...
449# 4. Kashgar...
450# ...
451# 5. It seems that Uyghurs in Urumqi has been using Xinjiang since at least the
452# 1960's. I know of one Han, now over 50, who grew up in the surrounding
453# countryside and used Xinjiang time as a child.
454#
455# 6. Likewise for Kashgar and the rest of south Xinjiang I don't know of any
456# start date for Xinjiang time.
457#
458# Without having access to local historical records, nor the ability to legally
459# publish them, I would go with October 1, 1949, when Xinjiang became the Uyghur
460# Autonomous Region under the PRC. (Before that Uyghurs, of course, would also
461# not be using Beijing time, but some local time.)

472# it is not [an] observatory, but the official meteorological agency of HK,

635# an MP who went on a hunger strike for 11 days to force discussion about it!
636# We have no details, but we'll guess they didn't move the clocks back in fall.

642#
643# From the BBC via Joseph S. Myers (2004-06-27):
644#
645# Georgia moved closer to Western Europe on Sunday...  The former Soviet
646# republic has changed its time zone back to that of Moscow.  As a result it
647# is now just four hours ahead of Greenwich Mean Time, rather than five hours

652# From Teimuraz Abashidze (2005-11-07):
653# Government of Georgia ... decided to NOT CHANGE daylight savings time on

655# Currently, we are in fact GMT +4:00, as before 30 October it was GMT
656# +3:00.... The problem is, there is NO FORMAL LAW or governmental document
657# about it.  As far as I can find, I was told, that there is no document,
658# because we just DIDN'T ISSUE document about switching to winter time....

775# Iran
776
777# From Roozbeh Pournader (2003-03-15):
778# This is an English translation of what I just found (originally in Persian).
779# The Gregorian dates in brackets are mine:
780#
781#	Official Newspaper No. 13548-1370/6/25 [1991-09-16]
782#	No. 16760/T233 H				1370/6/10 [1991-09-01]
783#
784#	The Rule About Change of the Official Time of the Country
785#
786#	The Board of Ministers, in the meeting dated 1370/5/23 [1991-08-14],
787#	based on the suggestion number 2221/D dated 1370/4/22 [1991-07-13]
788#	of the Country's Organization for Official and Employment Affairs,
789#	and referring to the law for equating the working hours of workers
790#	and officers in the whole country dated 1359/4/23 [1980-07-14], and
791#	for synchronizing the official times of the country, agreed that:
792#
793#	The official time of the country will should move forward one hour
794#	at the 24[:00] hours of the first day of Farvardin and should return
795#	to its previous state at the 24[:00] hours of the 30th day of
796#	Shahrivar.
797#
798#	First Deputy to the President - Hassan Habibi
799#
800# From personal experience, that agrees with what has been followed
801# for at least the last 5 years.  Before that, for a few years, the
802# date used was the first Thursday night of Farvardin and the last
803# Thursday night of Shahrivar, but I can't give exact dates....
804# I have also changed the abbreviations to what is considered correct
805# here in Iran, IRST for regular time and IRDT for daylight saving time.
806#
807# From Roozbeh Pournader (2005-04-05):
808# The text of the Iranian law, in effect since 1925, clearly mentions
809# that the true solar year is the measure, and there is no arithmetic
810# leap year calculation involved.  There has never been any serious
811# plan to change that law....
812#
813# From Paul Eggert (2006-03-22):
814# Go with Shanks & Pottenger before Sept. 1991, and with Pournader thereafter.
815# I used Ed Reingold's cal-persia in GNU Emacs 21.2 to check Persian dates,
816# stopping after 2037 when 32-bit time_t's overflow.
817# That cal-persia used Birashk's approximation, which disagrees with the solar
818# calendar predictions for the year 2025, so I corrected those dates by hand.
819#
820# From Oscar van Vlijmen (2005-03-30), writing about future
821# discrepancies between cal-persia and the Iranian calendar:
822# For 2091 solar-longitude-after yields 2091-03-20 08:40:07.7 UT for
823# the vernal equinox and that gets so close to 12:00 some local
824# Iranian time that the definition of the correct location needs to be
825# known exactly, amongst other factors.  2157 is even closer:
826# 2157-03-20 08:37:15.5 UT.  But the Gregorian year 2025 should give
827# no interpretation problem whatsoever.  By the way, another instant
828# in the near future where there will be a discrepancy between
829# arithmetical and astronomical Iranian calendars will be in 2058:
830# vernal equinox on 2058-03-20 09:03:05.9 UT.  The Java version of
831# Reingold's/Dershowitz' calculator gives correctly the Gregorian date
832# 2058-03-21 for 1 Farvardin 1437 (astronomical).
833#
834# From Steffen Thorsen (2006-03-22):
835# Several of my users have reported that Iran will not observe DST anymore:
836# http://www.irna.ir/en/news/view/line-17/0603193812164948.htm
837#
838# From Reuters (2007-09-16), with a heads-up from Jesper Norgaard Welen:
839# ... the Guardian Council ... approved a law on Sunday to re-introduce
840# daylight saving time ...
841# http://uk.reuters.com/article/oilRpt/idUKBLA65048420070916
842#
843# From Roozbeh Pournader (2007-11-05):
844# This is quoted from Official Gazette of the Islamic Republic of
845# Iran, Volume 63, Number 18242, dated Tuesday 1386/6/24
846# [2007-10-16]. I am doing the best translation I can:...
847# The official time of the country will be moved forward for one hour
848# on the 24 hours of the first day of the month of Farvardin and will
849# be changed back to its previous state on the 24 hours of the

910# Iraq
911#
912# From Jonathan Lennox (2000-06-12):
913# An article in this week's Economist ("Inside the Saddam-free zone", p. 50 in
914# the U.S. edition) on the Iraqi Kurds contains a paragraph:
915# "The three northern provinces ... switched their clocks this spring and
916# are an hour ahead of Baghdad."
917#
918# But Rives McDow (2000-06-18) quotes a contact in Iraqi-Kurdistan as follows:
919# In the past, some Kurdish nationalists, as a protest to the Iraqi
920# Government, did not adhere to daylight saving time.  They referred
921# to daylight saving as Saddam time.  But, as of today, the time zone
922# in Iraqi-Kurdistan is on standard time with Baghdad, Iraq.
923#
924# So we'll ignore the Economist's claim.

962# Israel
963
964# From Ephraim Silverberg (2001-01-11):
965#
966# I coined "IST/IDT" circa 1988.  Until then there were three
967# different abbreviations in use:
968#
969# JST  Jerusalem Standard Time [Danny Braniss, Hebrew University]
970# IZT  Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
971# EEST Eastern Europe Standard Time [used by almost everyone else]
972#
973# Since timezones should be called by country and not capital cities,
974# I ruled out JST.  As Israel is in Asia Minor and not Eastern Europe,
975# EEST was equally unacceptable.  Since "zonal" was not compatible with
976# any other timezone abbreviation, I felt that 'IST' was the way to go
977# and, indeed, it has received almost universal acceptance in timezone
978# settings in Israeli computers.
979#
980# In any case, I am happy to share timezone abbreviations with India,
981# high on my favorite-country list (and not only because my wife's
982# family is from India).

1027# From Ephraim Silverberg
1028# (1997-03-04, 1998-03-16, 1998-12-28, 2000-01-17, 2000-07-25, 2004-12-22,
1029# and 2005-02-17):
1030
1031# According to the Office of the Secretary General of the Ministry of
1032# Interior, there is NO set rule for Daylight-Savings/Standard time changes.
1033# One thing is entrenched in law, however: that there must be at least 150
1034# days of daylight savings time annually.  From 1993-1998, the change to
1035# daylight savings time was on a Friday morning from midnight IST to
1036# 1 a.m IDT; up until 1998, the change back to standard time was on a
1037# Saturday night from midnight daylight savings time to 11 p.m. standard
1038# time.  1996 is an exception to this rule where the change back to standard
1039# time took place on Sunday night instead of Saturday night to avoid
1040# conflicts with the Jewish New Year.  In 1999, the change to
1041# daylight savings time was still on a Friday morning but from
1042# 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
1043# was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for
1044# 1999 only.  In the year 2000, the change to daylight savings time was

1204
1205# `9:00' and `JST' is from Guy Harris.
1206
1207# From Paul Eggert (1995-03-06):
1208# Today's _Asahi Evening News_ (page 4) reports that Japan had
1209# daylight saving between 1948 and 1951, but ``the system was discontinued
1210# because the public believed it would lead to longer working hours.''
1211
1212# From Mayumi Negishi in the 2005-08-10 Japan Times
1213# <http://www.japantimes.co.jp/cgi-bin/getarticle.pl5?nn20050810f2.htm>:
1214# Occupation authorities imposed daylight-saving time on Japan on
1215# [1948-05-01]....  But lack of prior debate and the execution of
1216# daylight-saving time just three days after the bill was passed generated
1217# deep hatred of the concept....  The Diet unceremoniously passed a bill to
1218# dump the unpopular system in October 1951, less than a month after the San
1219# Francisco Peace Treaty was signed.  (A government poll in 1951 showed 53%
1220# of the Japanese wanted to scrap daylight-saving time, as opposed to 30% who
1221# wanted to keep it.)
1222
1223# From Paul Eggert (2006-03-22):
1224# Shanks & Pottenger write that DST in Japan during those years was as follows:
1225# Rule	NAME	FROM	TO	TYPE	IN	ON	AT	SAVE	LETTER/S

1230# but the only locations using it (for birth certificates, presumably, since
1231# their audience is astrologers) were US military bases.  For now, assume
1232# that for most purposes daylight-saving time was observed; otherwise, what
1233# would have been the point of the 1951 poll?
1234
1235# From Hideyuki Suzuki (1998-11-09):
1236# 'Tokyo' usually stands for the former location of Tokyo Astronomical
1237# Observatory: E 139 44' 40".90 (9h 18m 58s.727), N 35 39' 16".0.
1238# This data is from 'Rika Nenpyou (Chronological Scientific Tables) 1996'
1239# edited by National Astronomical Observatory of Japan....
1240# JST (Japan Standard Time) has been used since 1888-01-01 00:00 (JST).
1241# The law is enacted on 1886-07-07.
1242
1243# From Hideyuki Suzuki (1998-11-16):
1244# The ordinance No. 51 (1886) established "standard time" in Japan,
1245# which stands for the time on E 135 degree.
1246# In the ordinance No. 167 (1895), "standard time" was renamed to "central
1247# standard time".  And the same ordinance also established "western standard
1248# time", which stands for the time on E 120 degree....  But "western standard
1249# time" was abolished in the ordinance No. 529 (1937).  In the ordinance No.
1250# 167, there is no mention regarding for what place western standard time is
1251# standard....
1252#
1253# I wrote "ordinance" above, but I don't know how to translate.
1254# In Japanese it's "chokurei", which means ordinance from emperor.
1255
1256# Shanks & Pottenger claim JST in use since 1896, and that a few
1257# places (e.g. Ishigaki) use +0800; go with Suzuki.  Guess that all
1258# ordinances took effect on Jan 1.

1363# From Paul Eggert (1996-11-22):
1364# Andrew Evtichov (1996-04-13) writes that Kazakhstan
1365# stayed in sync with Moscow after 1990, and that Aqtobe (formerly Aktyubinsk)
1366# and Aqtau (formerly Shevchenko) are the largest cities in their zones.
1367# Guess that Aqtau and Aqtobe diverged in 1995, since that's the first time
1368# IATA SSIM mentions a third time zone in Kazakhstan.
1369
1370# From Paul Eggert (2006-03-22):
1371# German Iofis, ELSI, Almaty (2001-10-09) reports that Kazakhstan uses
1372# RussiaAsia rules, instead of switching at 00:00 as the IATA has it.
1373# Go with Shanks & Pottenger, who have them always using RussiaAsia rules.
1374# Also go with the following claims of Shanks & Pottenger:
1375#
1376# - Kazakhstan did not observe DST in 1991.
1377# - Qyzylorda switched from +5:00 to +6:00 on 1992-01-19 02:00.
1378# - Oral switched from +5:00 to +4:00 in spring 1989.

1380# <a href="http://www.kazsociety.org.uk/news/2005/03/30.htm">
1381# From Kazakhstan Embassy's News Bulletin #11 (2005-03-21):
1382# </a>
1383# The Government of Kazakhstan passed a resolution March 15 abolishing
1384# daylight saving time citing lack of economic benefits and health
1385# complications coupled with a decrease in productivity.
1386#
1387# From Branislav Kojic (in Astana) via Gwillim Law (2005-06-28):
1388# ... what happened was that the former Kazakhstan Eastern time zone
1389# was "blended" with the Central zone.  Therefore, Kazakhstan now has
1390# two time zones, and difference between them is one hour.  The zone
1391# closer to UTC is the former Western zone (probably still called the
1392# same), encompassing four provinces in the west: Aqtobe, Atyrau,
1393# Mangghystau, and West Kazakhstan.  The other zone encompasses
1394# everything else....  I guess that would make Kazakhstan time zones
1395# de jure UTC+5 and UTC+6 respectively.

1700# There it appears that flights between Choibalsan and Ulaanbatar arrive
1701# about 1:35 - 1:50 hours later in local clock time, no matter the
1702# direction, while Ulaanbaatar-Khvod takes 2 hours in the Eastern
1703# direction and 3:35 back, which indicates that Ulaanbatar and Khvod are
1704# in different time zones (like we know about), while Choibalsan and
1705# Ulaanbatar are in the same time zone (correction needed).

1777# 15th October each year".  This agrees with McDow's 04-07 at 00:00,
1778# but disagrees about the October transition, and makes it sound like
1779# it's not on a trial basis.  Also, the "between the first Saturday

1953# Palestine
1954
1955# From Amos Shapir (1998-02-15):
1956#
1957# From 1917 until 1948-05-15, all of Palestine, including the parts now
1958# known as the Gaza Strip and the West Bank, was under British rule.
1959# Therefore the rules given for Israel for that period, apply there too...
1960#
1961# The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
1962# (except a short occupation by Israel from 1956-11 till 1957-03, but no
1963# time zone was affected then).  It was never formally annexed to Egypt,
1964# though.
1965#
1966# The rest of Palestine was under Jordanian rule at that time, formally
1967# annexed in 1950 as the West Bank (and the word "Trans" was dropped from
1968# the country's previous name of "the Hashemite Kingdom of the
1969# Trans-Jordan").  So the rules for Jordan for that time apply.  Major
1970# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
1971# East Jerusalem.
1972#
1973# Both areas were occupied by Israel in June 1967, but not annexed (except
1974# for East Jerusalem).  They were on Israel time since then; there might
1975# have been a Military Governor's order about time zones, but I'm not aware
1976# of any (such orders may have been issued semi-annually whenever summer
1977# time was in effect, but maybe the legal aspect of time was just neglected).
1978#
1979# The Palestinian Authority was established in 1993, and got hold of most
1980# towns in the West Bank and Gaza by 1995.  I know that in order to
1981# demonstrate...independence, they have been switching to
1982# summer time and back on a different schedule than Israel's, but I don't
1983# know when this was started, or what algorithm is used (most likely the
1984# Jordanian one).
1985#
1986# To summarize, the table should probably look something like that:
1987#
1988# Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-
1989# ------------+-----------+-----------+-----------+-----------
1990# Israel      | Zion      | Zion      | Zion      | Zion
1991# West bank   | Zion      | Jordan    | Zion      | Jordan
1992# Gaza        | Zion      | Egypt     | Zion      | Jordan
1993#
1994# I guess more info may be available from the PA's web page (if/when they
1995# have one).
1996
1997# From Paul Eggert (2006-03-22):
1998# Shanks & Pottenger write that Gaza did not observe DST until 1957, but go
1999# with Shapir and assume that it observed DST from 1940 through 1947,
2000# and that it used Jordanian rules starting in 1996.
2001# We don't yet need a separate entry for the West Bank, since
2002# the only differences between it and Gaza that we know about
2003# occurred before our cutoff date of 1970.
2004# However, as we get more information, we may need to add entries
2005# for parts of the West Bank as they transitioned from Israel's rules
2006# to Palestine's rules.  If you have more info about this, please
2007# send it to tz@elsie.nci.nih.gov for incorporation into future editions.

2277# [The Tamil Tigers] never accepted the original 1996 time change and simply

2279# Time (GMT), in line with neighbor India.
2280# From Paul Eggert (2006-04-18):
2281# People who live in regions under Tamil control can use [TZ='Asia/Kolkata'],
2282# as that zone has agreed with the Tamil areas since our cutoff date of 1970.
2283
2284# From K Sethu (2006-04-25):
2285# I think the abbreviation LKT originated from the world of computers at
2286# the time of or subsequent to the time zone changes by SL Government
2287# twice in 1996 and probably SL Government or its standardization
2288# agencies never declared an abbreviation as a national standard.
2289#
2290# I recollect before the recent change the government annoucemments
2291# mentioning it as simply changing Sri Lanka Standard Time or Sri Lanka
2292# Time and no mention was made about the abbreviation.
2293#
2294# If we look at Sri Lanka Department of Government's "Official News
2295# Website of Sri Lanka" ... http://www.news.lk/ we can see that they
2296# use SLT as abbreviation in time stamp at the beginning of each news
2297# item....
2298#
2299# Within Sri Lanka I think LKT is well known among computer users and
2300# adminsitrators.  In my opinion SLT may not be a good choice because the
2301# nation's largest telcom / internet operator Sri Lanka Telcom is well
2302# known by that abbreviation - simply as SLT (there IP domains are
2303# slt.lk and sltnet.lk).
2304#
2305# But if indeed our government has adopted SLT as standard abbreviation
2306# (that we have not known so far) then  it is better that it be used for
2307# all computers.
2308
2309# From Paul Eggert (2006-04-25):
2310# One possibility is that we wait for a bit for the dust to settle down

2396# For everyone's info, I saw an IATA time zone change for [Syria] for
2397# this month (March 2008) in the last day or so...This is the data IATA
2398# are now using:

2411# http://www.sana.sy/eng/21/2008/03/11/165173.htm
2412# </a>...which reads (in part) "The Cabinet approved the suggestion of the
2413# Ministry of Electricity to begin daylight savings time on Friday April
2414# 4th, advancing clocks one hour ahead on midnight of Thursday April 3rd."
2415# Since Syria is two hours east of UTC, the 2200 and 2100 transition times
2416# shown above match up with midnight in Syria.
2417
2418# From Arthur David Olson (2008-03-18):
2419# My buest guess at a Syrian rule is "the Friday nearest April 1";
2420# coding that involves either using a "Mar Fri>=29" construct that old time zone
2421# compilers can't handle  or having multiple Rules (a la Israel).
2422# For now, use "Apr Fri>=1", and go with IATA on a uniform Sep 30 end.

2424# From Steffen Thorsen (2008-10-07):

2426# according to the following article in the Syrian Arab News Agency (SANA).
2427#
2428# The article is in Arabic, and seems to tell that they will go back to
2429# winter time on 2008-11-01 at 00:00 local daylight time (delaying/setting
