16# for recent time zone data is the International Air Transport

375# population of Xinjiang, typically use "Xinjiang time" which is two
376# hours behind Beijing time, or UTC +0600. The government of the Xinjiang
377# Uyghur Autonomous Region, (XAUR, or just Xinjiang for short) as well as
378# local governments such as the Urumqi city government use both times in
379# publications, referring to what is popularly called Xinjiang time as
380# "Urumqi time." When Uyghurs make an appointment in the Uyghur language
381# they almost invariably use Xinjiang time.
382#
383# (Their ethnic Han compatriots would typically have no clue of its
384# widespread use, however, because so extremely few of them are fluent in
385# Uyghur, comparable to the number of Anglo-Americans fluent in Navajo.)
386#
387# (...As with the rest of China there was a brief interval ending in 1990
388# or 1991 when summer time was in use. The confusion was severe, with
389# the province not having dual times but four times in use at the same
390# time. Some areas remained on standard Xinjiang time or Beijing time and
391# others moving their clocks ahead.)

409# With the risk of being redundant to previous answers these are the most common
410# English "transliterations" (w/o using non-English symbols):
411#
412# 1. Wulumuqi...
413# 2. Kashi...
414# 3. Urumqi...
415# 4. Kashgar...
416# ...
417# 5. It seems that Uyghurs in Urumqi has been using Xinjiang since at least the
418# 1960's. I know of one Han, now over 50, who grew up in the surrounding
419# countryside and used Xinjiang time as a child.
420#
421# 6. Likewise for Kashgar and the rest of south Xinjiang I don't know of any
422# start date for Xinjiang time.
423#
424# Without having access to local historical records, nor the ability to legally
425# publish them, I would go with October 1, 1949, when Xinjiang became the Uyghur
426# Autonomous Region under the PRC. (Before that Uyghurs, of course, would also
427# not be using Beijing time, but some local time.)

751#
752# The Board of Ministers, in the meeting dated 1370/5/23 [1991-08-14],
753# based on the suggestion number 2221/D dated 1370/4/22 [1991-07-13]
754# of the Country's Organization for Official and Employment Affairs,
755# and referring to the law for equating the working hours of workers
756# and officers in the whole country dated 1359/4/23 [1980-07-14], and
757# for synchronizing the official times of the country, agreed that:
758#
759# The official time of the country will should move forward one hour
760# at the 24[:00] hours of the first day of Farvardin and should return
761# to its previous state at the 24[:00] hours of the 30th day of
762# Shahrivar.
763#
764# First Deputy to the President - Hassan Habibi
765#
766# From personal experience, that agrees with what has been followed
767# for at least the last 5 years. Before that, for a few years, the
768# date used was the first Thursday night of Farvardin and the last
769# Thursday night of Shahrivar, but I can't give exact dates....
770# I have also changed the abbreviations to what is considered correct
771# here in Iran, IRST for regular time and IRDT for daylight saving time.

773# From Roozbeh Pournader (2005-04-05):
774# The text of the Iranian law, in effect since 1925, clearly mentions
775# that the true solar year is the measure, and there is no arithmetic
776# leap year calculation involved. There has never been any serious
777# plan to change that law....

781# I used Ed Reingold's cal-persia in GNU Emacs 21.2 to check Persian dates,
782# stopping after 2037 when 32-bit time_t's overflow.
783# That cal-persia used Birashk's approximation, which disagrees with the solar
784# calendar predictions for the year 2025, so I corrected those dates by hand.
785#
786# From Oscar van Vlijmen (2005-03-30), writing about future
787# discrepancies between cal-persia and the Iranian calendar:
788# For 2091 solar-longitude-after yields 2091-03-20 08:40:07.7 UT for
789# the vernal equinox and that gets so close to 12:00 some local
790# Iranian time that the definition of the correct location needs to be
791# known exactly, amongst other factors. 2157 is even closer:
792# 2157-03-20 08:37:15.5 UT. But the Gregorian year 2025 should give
793# no interpretation problem whatsoever. By the way, another instant
794# in the near future where there will be a discrepancy between
795# arithmetical and astronomical Iranian calendars will be in 2058:
796# vernal equinox on 2058-03-20 09:03:05.9 UT. The Java version of
797# Reingold's/Dershowitz' calculator gives correctly the Gregorian date
798# 2058-03-21 for 1 Farvardin 1437 (astronomical).

879# An article in this week's Economist ("Inside the Saddam-free zone", p. 50 in
880# the U.S. edition) on the Iraqi Kurds contains a paragraph:
881# "The three northern provinces ... switched their clocks this spring and
882# are an hour ahead of Baghdad."
883#
884# But Rives McDow (2000-06-18) quotes a contact in Iraqi-Kurdistan as follows:
885# In the past, some Kurdish nationalists, as a protest to the Iraqi
886# Government, did not adhere to daylight saving time. They referred
887# to daylight saving as Saddam time. But, as of today, the time zone
888# in Iraqi-Kurdistan is on standard time with Baghdad, Iraq.

930# From Ephraim Silverberg (2001-01-11):
931#
932# I coined "IST/IDT" circa 1988. Until then there were three
933# different abbreviations in use:
934#
935# JST Jerusalem Standard Time [Danny Braniss, Hebrew University]
936# IZT Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
937# EEST Eastern Europe Standard Time [used by almost everyone else]
938#
939# Since timezones should be called by country and not capital cities,
940# I ruled out JST. As Israel is in Asia Minor and not Eastern Europe,
941# EEST was equally unacceptable. Since "zonal" was not compatible with
942# any other timezone abbreviation, I felt that 'IST' was the way to go
943# and, indeed, it has received almost universal acceptance in timezone
944# settings in Israeli computers.
945#
946# In any case, I am happy to share timezone abbreviations with India,
947# high on my favorite-country list (and not only because my wife's
948# family is from India).

997# According to the Office of the Secretary General of the Ministry of
998# Interior, there is NO set rule for Daylight-Savings/Standard time changes.
999# One thing is entrenched in law, however: that there must be at least 150
1000# days of daylight savings time annually. From 1993-1998, the change to
1001# daylight savings time was on a Friday morning from midnight IST to
1002# 1 a.m IDT; up until 1998, the change back to standard time was on a
1003# Saturday night from midnight daylight savings time to 11 p.m. standard
1004# time. 1996 is an exception to this rule where the change back to standard
1005# time took place on Sunday night instead of Saturday night to avoid
1006# conflicts with the Jewish New Year. In 1999, the change to
1007# daylight savings time was still on a Friday morning but from
1008# 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
1009# was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for
1010# 1999 only. In the year 2000, the change to daylight savings time was
1011# similar to 1999, but although the change back will be on a Friday, it
1012# will take place from 1 a.m. IDT to midnight IST. Starting in 2001, all
1013# changes to/from will take place at 1 a.m. old time, but now there is no
1014# rule as to what day of the week it will take place in as the start date
1015# (except in 2003) is the night after the Passover Seder (i.e. the eve
1016# of the 16th of Nisan in the lunar Hebrew calendar) and the end date
1017# (except in 2002) is three nights before Yom Kippur [Day of Atonement]

1730# From Rives McDow (2002-03-13):
1731# I have been advised that Pakistan has decided to adopt dst on a
1732# TRIAL basis for one year, starting 00:01 local time on April 7, 2002
1733# and ending at 00:01 local time October 6, 2002. This is what I was
1734# told, but I believe that the actual time of change may be 00:00; the
1735# 00:01 was to make it clear which day it was on.

1739# http://www.pak.gov.pk/public/news/app/app06_dec.htm
1740# (dated 2001-12-06) which says that the Cabinet adopted a scheme "to
1741# advance the clocks by one hour on the night between the first
1742# Saturday and Sunday of April and revert to the original position on
1743# 15th October each year". This agrees with McDow's 04-07 at 00:00,
1744# but disagrees about the October transition, and makes it sound like
1745# it's not on a trial basis. Also, the "between the first Saturday
1746# and Sunday of April" phrase, if taken literally, means that the
1747# transition takes place at 00:00 on the first Sunday on or after 04-02.

9ffe4b14 1899# From Amos Shapir (1998-02-15):
984263bc
MD
1900#
1901# From 1917 until 1948-05-15, all of Palestine, including the parts now
1902# known as the Gaza Strip and the West Bank, was under British rule.
1903# Therefore the rules given for Israel for that period, apply there too...
1904#
1905# The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
1906# (except a short occupation by Israel from 1956-11 till 1957-03, but no
1907# time zone was affected then). It was never formally annexed to Egypt,
1908# though.
1909#
1910# The rest of Palestine was under Jordanian rule at that time, formally
1911# annexed in 1950 as the West Bank (and the word "Trans" was dropped from
1912# the country's previous name of "the Hashemite Kingdom of the
1913# Trans-Jordan"). So the rules for Jordan for that time apply. Major
1914# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
1915# East Jerusalem.
1916#
1917# Both areas were occupied by Israel in June 1967, but not annexed (except
1918# for East Jerusalem). They were on Israel time since then; there might
1919# have been a Military Governor's order about time zones, but I'm not aware
1920# of any (such orders may have been issued semi-annually whenever summer
1921# time was in effect, but maybe the legal aspect of time was just neglected).
1922#
1923# The Palestinian Authority was established in 1993, and got hold of most
1924# towns in the West Bank and Gaza by 1995. I know that in order to
1925# demonstrate...independence, they have been switching to
1926# summer time and back on a different schedule than Israel's, but I don't
1927# know when this was started, or what algorithm is used (most likely the
1928# Jordanian one).
1929#
1930# To summarize, the table should probably look something like that:
1931#
1932# Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-
1933# ------------+-----------+-----------+-----------+-----------
1934# Israel | Zion | Zion | Zion | Zion
1935# West bank | Zion | Jordan | Zion | Jordan
1936# Gaza | Zion | Egypt | Zion | Jordan
1937#
1938# I guess more info may be available from the PA's web page (if/when they
1939# have one).

1943# with Shapir and assume that it observed DST from 1940 through 1947,
1944# and that it used Jordanian rules starting in 1996.
1945# We don't yet need a separate entry for the West Bank, since
1946# the only differences between it and Gaza that we know about
1947# occurred before our cutoff date of 1970.
1948# However, as we get more information, we may need to add entries
1949# for parts of the West Bank as they transitioned from Israel's rules
1950# to Palestine's rules. If you have more info about this, please

2194# [The Tamil Tigers] never accepted the original 1996 time change and simply

2200
2201# From K Sethu (2006-04-25):
2202# I think the abbreviation LKT originated from the world of computers at
2203# the time of or subsequent to the time zone changes by SL Government
2204# twice in 1996 and probably SL Government or its standardization
2205# agencies never declared an abbreviation as a national standard.
2206#
2207# I recollect before the recent change the government annoucemments
2208# mentioning it as simply changing Sri Lanka Standard Time or Sri Lanka
2209# Time and no mention was made about the abbreviation.
2210#
2211# If we look at Sri Lanka Department of Government's "Official News
2212# Website of Sri Lanka" ... http://www.news.lk/ we can see that they
2213# use SLT as abbreviation in time stamp at the beginning of each news
2214# item....
2215#
2216# Within Sri Lanka I think LKT is well known among computer users and
2217# adminsitrators. In my opinion SLT may not be a good choice because the
2218# nation's largest telcom / internet operator Sri Lanka Telcom is well
2219# known by that abbreviation - simply as SLT (there IP domains are
2220# slt.lk and sltnet.lk).
2221#
2222# But if indeed our government has adopted SLT as standard abbreviation
2223# (that we have not known so far) then it is better that it be used for
2224# all computers.
2225
2226# From Paul Eggert (2006-04-25):
2227# One possibility is that we wait for a bit for the dust to settle down
