|
|
|
|
|

# what is called "Beijing time." When Han make an appointment in Chinese
|
|
|
|
|
# they implicitly use Beijing time.
|
|
|
|
|
#
|
|
|
|
|
# On the other hand, ethnic Uyghurs, who make up about half the
|
|
|
|
|
# population of Xinjiang, typically use "Xinjiang time" which is two
|
|
|
|
|
# hours behind Beijing time, or UTC +0600. The government of the Xinjiang
|
|
|
|
|
# Uyghur Autonomous Region, (XAUR, or just Xinjiang for short) as well as
|
|
|
|
|
# local governments such as the Urumqi city government use both times in
|
|

# publications, referring to what is popularly called Xinjiang time as
|
|
|
|
|
# "Urumqi time." When Uyghurs make an appointment in the Uyghur language
|
|
|
|
|
# they almost invariably use Xinjiang time.

|
|
|
|
#
|
|
|
|
|
# (Their ethnic Han compatriots would typically have no clue of its
|
|
|
|

|
|
|
|
|
# an MP who went on a hunger strike for 11 days to force discussion about it!

# We have no details, but we'll guess they didn't move the clocks back in fall.

#
|

# From Mathew Englander, quoting AP (1996-10-23 13:05-04):

|
|
# Instead of putting back clocks at the end of October, Georgia
|
|
|

# will stay on daylight savings time this winter to save energy,
|

#
|
|
|
|
|
# Georgia moved closer to Western Europe on Sunday... The former Soviet
|
|
|
|
|
# republic has changed its time zone back to that of Moscow. As a result it
|
|
|
|
|
# is now just four hours ahead of Greenwich Mean Time, rather than five hours
|
|
|
|
|
# ahead. The switch was decreed by the pro-Western president of Georgia,
|
|

# Mikhail Saakashvili, who said the change was partly prompted by the process
|
|
|
|
|
# of integration into Europe.

# From Teimuraz Abashidze (2005-11-07):

|
|
|
|
|
# [Oct.] 30, as it was done before during last more than 10 years.
|
|
|
|
|
# Currently, we are in fact GMT +4:00, as before 30 October it was GMT
|
|
|
|
|
# +3:00.... The problem is, there is NO FORMAL LAW or governmental document
|
|
|
|
|
# about it. As far as I can find, I was told, that there is no document,
|
|
|
|
|
# because we just DIDN'T ISSUE document about switching to winter time....

# I don't know what can be done, especially knowing that some years ago our

# Go with Shanks & Pottenger before Sept. 1991, and with Pournader thereafter.

|
|
|
# stopping after 2037 when 32-bit time_t's overflow.
|
|
|
|
|
# That cal-persia used Birashk's approximation, which disagrees with the solar

# discrepancies between cal-persia and the Iranian calendar:
|
|
|
|
|
# For 2091 solar-longitude-after yields 2091-03-20 08:40:07.7 UT for
|
|
|
|
|
# the vernal equinox and that gets so close to 12:00 some local
|
|
|
|
|
# Iranian time that the definition of the correct location needs to be
|
|

|
# known exactly, amongst other factors. 2157 is even closer:
|
|
|
|
|
# 2157-03-20 08:37:15.5 UT. But the Gregorian year 2025 should give
|
|
|
|
|
# no interpretation problem whatsoever. By the way, another instant
|
|
|
|
|
# in the near future where there will be a discrepancy between

# arithmetical and astronomical Iranian calendars will be in 2058:

# vernal equinox on 2058-03-20 09:03:05.9 UT. The Java version of

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

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

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

# deep hatred of the concept.... The Diet unceremoniously passed a bill to

|
# In the ordinance No. 167 (1895), "standard time" was renamed to "central

|

|
|
|
# time", which stands for the time on E 120 degree.... But "western standard
|
|
|
|
|
# time" was abolished in the ordinance No. 529 (1937). In the ordinance No.
|
|

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

# Palestine
|
|
|
|
|
|
|
|
|
|
# From Amos Shapir (1998-02-15):
|
|
|
|
|
#
|
|
|
|
|
# From 1917 until 1948-05-15, all of Palestine, including the parts now
|
|
|
|
|
# known as the Gaza Strip and the West Bank, was under British rule.
|
|
|
|
|
# Therefore the rules given for Israel for that period, apply there too...
|
|
|
|
|
#
|
|
|
|
|
# The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
|
|
|
|
|
# (except a short occupation by Israel from 1956-11 till 1957-03, but no
|
|
|
|
|
# time zone was affected then). It was never formally annexed to Egypt,
|
|
|
|
|
# though.
|
|
|
|
|
#
|
|
|
|
|
# The rest of Palestine was under Jordanian rule at that time, formally
|
|
|
|
|
# annexed in 1950 as the West Bank (and the word "Trans" was dropped from
|
|
|
|
|
# the country's previous name of "the Hashemite Kingdom of the
|
|
|
|
|
# Trans-Jordan"). So the rules for Jordan for that time apply. Major
|
|
|
|
|
# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
|
|
|
|
|
# East Jerusalem.
|
|
|
|
|
#
|
|
|
|
|
# Both areas were occupied by Israel in June 1967, but not annexed (except
|
|
|
|
|
# for East Jerusalem). They were on Israel time since then; there might
|
|
|
|
|
# have been a Military Governor's order about time zones, but I'm not aware
|
|
|
|
|
# of any (such orders may have been issued semi-annually whenever summer
|
|
|
|
|
# time was in effect, but maybe the legal aspect of time was just neglected).
|
|
|
|
|
#
|
|
|
|
|
# The Palestinian Authority was established in 1993, and got hold of most
|
|
|
|
|
# towns in the West Bank and Gaza by 1995. I know that in order to
|
|
|
|
|
# demonstrate...independence, they have been switching to
|
|
|
|
|
# summer time and back on a different schedule than Israel's, but I don't
|
|
|
|
|
# know when this was started, or what algorithm is used (most likely the
|
|
|
|
|
# Jordanian one).
|
|
|
|
|
#
|
|

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

|
|
|
|
|
# twice in 1996 and probably SL Government or its standardization
|
|
|
|
|
# agencies never declared an abbreviation as a national standard.
|
|
|
|
|
#
|
|
|
|
|
# I recollect before the recent change the government annoucemments
|
|
|
|
|
# mentioning it as simply changing Sri Lanka Standard Time or Sri Lanka
|
|
|
|
|
# Time and no mention was made about the abbreviation.
|
|
|
|
|
#
|
|
|
|
|
# If we look at Sri Lanka Department of Government's "Official News
|
|
|
|

# Website of Sri Lanka" ... http://www.news.lk/ we can see that they

|

|
#
|
|
|
|
|
# Within Sri Lanka I think LKT is well known among computer users and

|
# adminsitrators. In my opinion SLT may not be a good choice because the

# nation's largest telcom / internet operator Sri Lanka Telcom is well
