416# From Luther Ma (2009-10-17):
417# Almost all (>99.9%) ethnic Chinese (properly ethnic Han) living in
418# Xinjiang use Chinese Standard Time. Some are aware of Xinjiang time,
419# but have no need of it. All planes, trains, and schools function on
420# what is called "Beijing time." When Han make an appointment in Chinese
421# they implicitly use Beijing time.
422#
423# On the other hand, ethnic Uyghurs, who make up about half the
424# population of Xinjiang, typically use "Xinjiang time" which is two
425# hours behind Beijing time, or UTC +0600. The government of the Xinjiang
426# Uyghur Autonomous Region, (XAUR, or just Xinjiang for short) as well as
427# local governments such as the Urumqi city government use both times in
428# publications, referring to what is popularly called Xinjiang time as
429# "Urumqi time." When Uyghurs make an appointment in the Uyghur language
430# they almost invariably use Xinjiang time.
431#
432# (Their ethnic Han compatriots would typically have no clue of its
433# widespread use, however, because so extremely few of them are fluent in
434# Uyghur, comparable to the number of Anglo-Americans fluent in Navajo.)
435#
436# (...As with the rest of China there was a brief interval ending in 1990
437# or 1991 when summer time was in use. The confusion was severe, with
438# the province not having dual times but four times in use at the same
439# time. Some areas remained on standard Xinjiang time or Beijing time and
440# others moving their clocks ahead.)
441#

458# With the risk of being redundant to previous answers these are the most common
459# English "transliterations" (w/o using non-English symbols):
460#
461# 1. Wulumuqi...
462# 2. Kashi...
463# 3. Urumqi...
464# 4. Kashgar...
465# ...
466# 5. It seems that Uyghurs in Urumqi has been using Xinjiang since at least the
467# 1960's. I know of one Han, now over 50, who grew up in the surrounding
468# countryside and used Xinjiang time as a child.
469#
470# 6. Likewise for Kashgar and the rest of south Xinjiang I don't know of any
471# start date for Xinjiang time.
472#
473# Without having access to local historical records, nor the ability to legally
474# publish them, I would go with October 1, 1949, when Xinjiang became the Uyghur
475# Autonomous Region under the PRC. (Before that Uyghurs, of course, would also
476# not be using Beijing time, but some local time.)

771# JohnTWB writes that Japanese forces did not surrender control in

773# other formal surrender ceremonies were September 9, 11, and 13, plus

823#
824# The Board of Ministers, in the meeting dated 1370/5/23 [1991-08-14],
825# based on the suggestion number 2221/D dated 1370/4/22 [1991-07-13]
826# of the Country's Organization for Official and Employment Affairs,
827# and referring to the law for equating the working hours of workers
828# and officers in the whole country dated 1359/4/23 [1980-07-14], and
829# for synchronizing the official times of the country, agreed that:
830#
831# The official time of the country will should move forward one hour
832# at the 24[:00] hours of the first day of Farvardin and should return
833# to its previous state at the 24[:00] hours of the 30th day of
834# Shahrivar.
835#
836# First Deputy to the President - Hassan Habibi
837#
838# From personal experience, that agrees with what has been followed
839# for at least the last 5 years. Before that, for a few years, the
840# date used was the first Thursday night of Farvardin and the last
841# Thursday night of Shahrivar, but I can't give exact dates....

853# I used Ed Reingold's cal-persia in GNU Emacs 21.2 to check Persian dates,
854# stopping after 2037 when 32-bit time_t's overflow.
855# That cal-persia used Birashk's approximation, which disagrees with the solar
856# calendar predictions for the year 2025, so I corrected those dates by hand.
857#
858# From Oscar van Vlijmen (2005-03-30), writing about future
859# discrepancies between cal-persia and the Iranian calendar:
860# For 2091 solar-longitude-after yields 2091-03-20 08:40:07.7 UT for
861# the vernal equinox and that gets so close to 12:00 some local
862# Iranian time that the definition of the correct location needs to be
863# known exactly, amongst other factors. 2157 is even closer:
864# 2157-03-20 08:37:15.5 UT. But the Gregorian year 2025 should give
865# no interpretation problem whatsoever. By the way, another instant
866# in the near future where there will be a discrepancy between
867# arithmetical and astronomical Iranian calendars will be in 2058:
868# vernal equinox on 2058-03-20 09:03:05.9 UT. The Java version of
869# Reingold's/Dershowitz' calculator gives correctly the Gregorian date
870# 2058-03-21 for 1 Farvardin 1437 (astronomical).

951# An article in this week's Economist ("Inside the Saddam-free zone", p. 50 in

953# "The three northern provinces ... switched their clocks this spring and

1002# From Ephraim Silverberg (2001-01-11):
1003#
1004# I coined "IST/IDT" circa 1988. Until then there were three
1005# different abbreviations in use:
1006#
1007# JST Jerusalem Standard Time [Danny Braniss, Hebrew University]
1008# IZT Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
1009# EEST Eastern Europe Standard Time [used by almost everyone else]
1010#
1011# Since timezones should be called by country and not capital cities,
1012# I ruled out JST. As Israel is in Asia Minor and not Eastern Europe,
1013# EEST was equally unacceptable. Since "zonal" was not compatible with
1014# any other timezone abbreviation, I felt that 'IST' was the way to go
1015# and, indeed, it has received almost universal acceptance in timezone
1016# settings in Israeli computers.
1017#
1018# In any case, I am happy to share timezone abbreviations with India,
1019# high on my favorite-country list (and not only because my wife's
1020# family is from India).

1069# According to the Office of the Secretary General of the Ministry of
1070# Interior, there is NO set rule for Daylight-Savings/Standard time changes.
1071# One thing is entrenched in law, however: that there must be at least 150
1072# days of daylight savings time annually. From 1993-1998, the change to
1073# daylight savings time was on a Friday morning from midnight IST to
1074# 1 a.m IDT; up until 1998, the change back to standard time was on a
1075# Saturday night from midnight daylight savings time to 11 p.m. standard
1076# time. 1996 is an exception to this rule where the change back to standard
1077# time took place on Sunday night instead of Saturday night to avoid
1078# conflicts with the Jewish New Year. In 1999, the change to
1079# daylight savings time was still on a Friday morning but from
1080# 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
1081# was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for
1082# 1999 only. In the year 2000, the change to daylight savings time was
1083# similar to 1999, but although the change back will be on a Friday, it
1084# will take place from 1 a.m. IDT to midnight IST. Starting in 2001, all
1085# changes to/from will take place at 1 a.m. old time, but now there is no
1086# rule as to what day of the week it will take place in as the start date
1087# (except in 2003) is the night after the Passover Seder (i.e. the eve
1088# of the 16th of Nisan in the lunar Hebrew calendar) and the end date
1089# (except in 2002) is three nights before Yom Kippur [Day of Atonement]
1090# (the eve of the 7th of Tishrei in the lunar Hebrew calendar).

1252# Occupation authorities imposed daylight-saving time on Japan on

1428# two time zones, and difference between them is one hour. The zone
1429# closer to UTC is the former Western zone (probably still called the

1803# I have been advised that Pakistan has decided to adopt dst on a

1805# and ending at 00:01 local time October 6, 2002. This is what I was

1815# 15th October each year". This agrees with McDow's 04-07 at 00:00,
1816# but disagrees about the October transition, and makes it sound like
1817# it's not on a trial basis. Also, the "between the first Saturday

984263bc
MD
1994#
1995# From 1917 until 1948-05-15, all of Palestine, including the parts now
1996# known as the Gaza Strip and the West Bank, was under British rule.
1997# Therefore the rules given for Israel for that period, apply there too...
1998#
1999# The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
2000# (except a short occupation by Israel from 1956-11 till 1957-03, but no
2001# time zone was affected then). It was never formally annexed to Egypt,
2002# though.
2003#
2004# The rest of Palestine was under Jordanian rule at that time, formally
2005# annexed in 1950 as the West Bank (and the word "Trans" was dropped from
2006# the country's previous name of "the Hashemite Kingdom of the
2007# Trans-Jordan"). So the rules for Jordan for that time apply. Major
2008# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
2009# East Jerusalem.
2010#
2011# Both areas were occupied by Israel in June 1967, but not annexed (except
2012# for East Jerusalem). They were on Israel time since then; there might
2013# have been a Military Governor's order about time zones, but I'm not aware
2014# of any (such orders may have been issued semi-annually whenever summer
2015# time was in effect, but maybe the legal aspect of time was just neglected).
2016#
2017# The Palestinian Authority was established in 1993, and got hold of most
2018# towns in the West Bank and Gaza by 1995. I know that in order to
2019# demonstrate...independence, they have been switching to
2020# summer time and back on a different schedule than Israel's, but I don't
2021# know when this was started, or what algorithm is used (most likely the
2022# Jordanian one).
2023#
2024# To summarize, the table should probably look something like that:
2025#
2026# Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-

2408# From Jesper Norgaard Welen (2006-04-14), quoting Sri Lanka News Online
2409# <http://news.sinhalaya.com/wmview.php?ArtID=11002> (2006-04-13):

2413# From Peter Apps and Ranga Sirila of Reuters (2006-04-12) in:
2414# <http://today.reuters.co.uk/news/newsArticle.aspx?type=scienceNews&storyID=2006-04-12T172228Z_01_COL295762_RTRIDST_0_SCIENCE-SRILANKA-TIME-DC.XML>
2415# [The Tamil Tigers] never accepted the original 1996 time change and simply
2416# kept their clocks set five and a half hours ahead of Greenwich Mean
2417# Time (GMT), in line with neighbor India.
2418# From Paul Eggert (2006-04-18):
e4a74243 2419# People who live in regions under Tamil control can use [TZ='Asia/Kolkata'],
bd7414aa
SW
2420# as that zone has agreed with the Tamil areas since our cutoff date of 1970.
2421
2422# From K Sethu (2006-04-25):
2423# I think the abbreviation LKT originated from the world of computers at
2424# the time of or subsequent to the time zone changes by SL Government
2425# twice in 1996 and probably SL Government or its standardization
2426# agencies never declared an abbreviation as a national standard.
2427#
2428# I recollect before the recent change the government annoucemments
2429# mentioning it as simply changing Sri Lanka Standard Time or Sri Lanka
2430# Time and no mention was made about the abbreviation.
2431#
2432# If we look at Sri Lanka Department of Government's "Official News
2433# Website of Sri Lanka" ... http://www.news.lk/ we can see that they
2434# use SLT as abbreviation in time stamp at the beginning of each news
2435# item....
2436#
2437# Within Sri Lanka I think LKT is well known among computer users and
2438# adminsitrators. In my opinion SLT may not be a good choice because the
2439# nation's largest telcom / internet operator Sri Lanka Telcom is well
2440# known by that abbreviation - simply as SLT (there IP domains are
2441# slt.lk and sltnet.lk).
2442#
2443# But if indeed our government has adopted SLT as standard abbreviation
2444# (that we have not known so far) then it is better that it be used for
2445# all computers.
2446
2447# From Paul Eggert (2006-04-25):
2448# One possibility is that we wait for a bit for the dust to settle down
2449# and then see what people actually say in practice.
