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

230# No they don't. See TIME mag, 1986-02-17 p.52. Even though
231# China is across 4 physical time zones, before Feb 1, 1986 only the
232# Peking (Bejing) time zone was recognized. Since that date, China
233# has two of 'em -- Peking's and Urumqi (named after the capital of

626#
627# From Oscar van Vlijmen (2005-03-30), writing about future

629# For 2091 solar-longitude-after yields 2091-03-20 08:40:07.7 UT for
630# the vernal equinox and that gets so close to 12:00 some local
631# Iranian time that the definition of the correct location needs to be
632# known exactly, amongst other factors. 2157 is even closer:
633# 2157-03-20 08:37:15.5 UT. But the Gregorian year 2025 should give
634# no interpretation problem whatsoever. By the way, another instant
635# in the near future where there will be a discrepancy between
636# arithmetical and astronomical Iranian calendars will be in 2058:
637# vernal equinox on 2058-03-20 09:03:05.9 UT. The Java version of

720# An article in this week's Economist ("Inside the Saddam-free zone", p. 50 in
721# the U.S. edition) on the Iraqi Kurds contains a paragraph:
722# "The three northern provinces ... switched their clocks this spring and
723# are an hour ahead of Baghdad."
724#
725# But Rives McDow (2000-06-18) quotes a contact in Iraqi-Kurdistan as follows:
726# In the past, some Kurdish nationalists, as a protest to the Iraqi
727# Government, did not adhere to daylight saving time. They referred
728# to daylight saving as Saddam time. But, as of today, the time zone
729# in Iraqi-Kurdistan is on standard time with Baghdad, Iraq.
730#
731# So we'll ignore the Economist's claim.

771# From Ephraim Silverberg (2001-01-11):
772#
773# I coined "IST/IDT" circa 1988. Until then there were three
774# different abbreviations in use:
775#
776# JST Jerusalem Standard Time [Danny Braniss, Hebrew University]
777# IZT Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
778# EEST Eastern Europe Standard Time [used by almost everyone else]
779#
780# Since timezones should be called by country and not capital cities,
781# I ruled out JST. As Israel is in Asia Minor and not Eastern Europe,
782# EEST was equally unacceptable. Since "zonal" was not compatible with
783# any other timezone abbreviation, I felt that 'IST' was the way to go
784# and, indeed, it has received almost universal acceptance in timezone
785# settings in Israeli computers.
786#
787# In any case, I am happy to share timezone abbreviations with India,
788# high on my favorite-country list (and not only because my wife's
789# family is from India).

837
838# According to the Office of the Secretary General of the Ministry of
839# Interior, there is NO set rule for Daylight-Savings/Standard time changes.
840# One thing is entrenched in law, however: that there must be at least 150
841# days of daylight savings time annually. From 1993-1998, the change to
842# daylight savings time was on a Friday morning from midnight IST to
843# 1 a.m IDT; up until 1998, the change back to standard time was on a
844# Saturday night from midnight daylight savings time to 11 p.m. standard
845# time. 1996 is an exception to this rule where the change back to standard
846# time took place on Sunday night instead of Saturday night to avoid
847# conflicts with the Jewish New Year. In 1999, the change to
848# daylight savings time was still on a Friday morning but from
849# 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
850# was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for
851# 1999 only. In the year 2000, the change to daylight savings time was
852# similar to 1999, but although the change back will be on a Friday, it
853# will take place from 1 a.m. IDT to midnight IST. Starting in 2001, all
854# changes to/from will take place at 1 a.m. old time, but now there is no
855# rule as to what day of the week it will take place in as the start date
856# (except in 2003) is the night after the Passover Seder (i.e. the eve
857# of the 16th of Nisan in the lunar Hebrew calendar) and the end date
858# (except in 2002) is three nights before Yom Kippur [Day of Atonement]
859# (the eve of the 7th of Tishrei in the lunar Hebrew calendar).

1051# The ordinance No. 51 (1886) established "standard time" in Japan,

1053# In the ordinance No. 167 (1895), "standard time" was renamed to "central
1054# standard time". And the same ordinance also established "western standard
1055# time", which stands for the time on E 120 degree.... But "western standard
1056# time" was abolished in the ordinance No. 529 (1937). In the ordinance No.
1057# 167, there is no mention regarding for what place western standard time is
1058# standard....

1060# I wrote "ordinance" above, but I don't know how to translate.

1691#
1692# From 1917 until 1948-05-15, all of Palestine, including the parts now
1693# known as the Gaza Strip and the West Bank, was under British rule.
1694# Therefore the rules given for Israel for that period, apply there too...
1695#
1696# The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
1697# (except a short occupation by Israel from 1956-11 till 1957-03, but no
1698# time zone was affected then). It was never formally annexed to Egypt,
1699# though.
1700#
1701# The rest of Palestine was under Jordanian rule at that time, formally
1702# annexed in 1950 as the West Bank (and the word "Trans" was dropped from
1703# the country's previous name of "the Hashemite Kingdom of the
1704# Trans-Jordan"). So the rules for Jordan for that time apply. Major
1705# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
1706# East Jerusalem.
1707#
1708# Both areas were occupied by Israel in June 1967, but not annexed (except
1709# for East Jerusalem). They were on Israel time since then; there might
1710# have been a Military Governor's order about time zones, but I'm not aware
1711# of any (such orders may have been issued semi-annually whenever summer
1712# time was in effect, but maybe the legal aspect of time was just neglected).
1713#
1714# The Palestinian Authority was established in 1993, and got hold of most
1715# towns in the West Bank and Gaza by 1995. I know that in order to

1956# From K Sethu (2006-04-25):
1957# I think the abbreviation LKT originated from the world of computers at
1958# the time of or subsequent to the time zone changes by SL Government
1959# twice in 1996 and probably SL Government or its standardization
1960# agencies never declared an abbreviation as a national standard.
1961#
1962# I recollect before the recent change the government annoucemments
1963# mentioning it as simply changing Sri Lanka Standard Time or Sri Lanka
1964# Time and no mention was made about the abbreviation.
1965#
1966# If we look at Sri Lanka Department of Government's "Official News
1967# Website of Sri Lanka" ... http://www.news.lk/ we can see that they
1968# use SLT as abbreviation in time stamp at the beginning of each news
1969# item....
1970#
1971# Within Sri Lanka I think LKT is well known among computer users and
1972# adminsitrators. In my opinion SLT may not be a good choice because the
1973# nation's largest telcom / internet operator Sri Lanka Telcom is well
1974# known by that abbreviation - simply as SLT (there IP domains are
1975# slt.lk and sltnet.lk).
1976#
1977# But if indeed our government has adopted SLT as standard abbreviation

1979# all computers.
