  7. # From Paul Eggert (2006-03-22):
  8. #
  9. # A good source for time zone historical data outside the U.S. is
  10. # Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
  11. # San Diego: ACS Publications, Inc. (2003).
  12. #
  13. # Gwillim Law writes that a good source
  14. # for recent time zone data is the International Air Transport
  15. # Association's Standard Schedules Information Manual (IATA SSIM),
  16. # published semiannually. Law sent in several helpful summaries
  17. # of the IATA's data after 1990.
  18. #
  19. # Except where otherwise noted, Shanks & Pottenger is the source for
  20. # entries through 1990, and IATA SSIM is the source for entries afterwards.
  21. #
  22. # Another source occasionally used is Edward W. Whitman, World Time Differences,
  23. # Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
  24. # I found in the UCLA library.
  25. #
  26. # A reliable and entertaining source about time zones is
  27. # Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997).

  80. # From Paul Eggert (2006-03-22):

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

  85. # reported (1996-05-04) that Yerevan probably wouldn't use DST
  86. # in 1996, though it did use DST in 1995. IATA SSIM (1991/1998) reports that

  390. # hours behind Beijing time, or UTC +0600. The government of the Xinjiang
  391. # Uyghur Autonomous Region, (XAUR, or just Xinjiang for short) as well as
  392. # local governments such as the Urumqi city government use both times in
  393. # publications, referring to what is popularly called Xinjiang time as
  394. # "Urumqi time." When Uyghurs make an appointment in the Uyghur language
  395. # they almost invariably use Xinjiang time.

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

  401. # (...As with the rest of China there was a brief interval ending in 1990

  796. # known exactly, amongst other factors. 2157 is even closer:
  797. # 2157-03-20 08:37:15.5 UT. But the Gregorian year 2025 should give
  798. # no interpretation problem whatsoever. By the way, another instant

  881. # From Jonathan Lennox (2000-06-12):
  882. # An article in this week's Economist ("Inside the Saddam-free zone", p. 50 in
  883. # the U.S. edition) on the Iraqi Kurds contains a paragraph:
  884. # "The three northern provinces ... switched their clocks this spring and
  885. # are an hour ahead of Baghdad."
  886. #
  887. # But Rives McDow (2000-06-18) quotes a contact in Iraqi-Kurdistan as follows:
  888. # In the past, some Kurdish nationalists, as a protest to the Iraqi
  889. # Government, did not adhere to daylight saving time. They referred
  890. # to daylight saving as Saddam time. But, as of today, the time zone
  891. # in Iraqi-Kurdistan is on standard time with Baghdad, Iraq.
  892. #
  893. # So we'll ignore the Economist's claim.

  927. # From Ephraim Silverberg (2001-01-11):
  928. #
  929. # I coined "IST/IDT" circa 1988. Until then there were three
  930. # different abbreviations in use:
  931. #
  932. # JST Jerusalem Standard Time [Danny Braniss, Hebrew University]
  933. # IZT Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
  934. # EEST Eastern Europe Standard Time [used by almost everyone else]
  935. #
  936. # Since timezones should be called by country and not capital cities,
  937. # I ruled out JST. As Israel is in Asia Minor and not Eastern Europe,
  938. # EEST was equally unacceptable. Since "zonal" was not compatible with
  939. # any other timezone abbreviation, I felt that 'IST' was the way to go
  940. # and, indeed, it has received almost universal acceptance in timezone
  941. # settings in Israeli computers.
  942. #
  943. # In any case, I am happy to share timezone abbreviations with India,
  944. # high on my favorite-country list (and not only because my wife's
  945. # family is from India).

  989. # (1997-03-04, 1998-03-16, 1998-12-28, 2000-01-17, 2000-07-25, 2004-12-22,
  990. # and 2005-02-17):
  991. # According to the Office of the Secretary General of the Ministry of
  992. # Interior, there is NO set rule for Daylight-Savings/Standard time changes.
  993. # One thing is entrenched in law, however: that there must be at least 150
  994. # days of daylight savings time annually. From 1993-1998, the change to
  995. # daylight savings time was on a Friday morning from midnight IST to
  996. # 1 a.m IDT; up until 1998, the change back to standard time was on a
  997. # Saturday night from midnight daylight savings time to 11 p.m. standard
  998. # time. 1996 is an exception to this rule where the change back to standard
  999. # time took place on Sunday night instead of Saturday night to avoid
  1000. # conflicts with the Jewish New Year. In 1999, the change to
  1001. # daylight savings time was still on a Friday morning but from
  1002. # 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
  1003. # was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for
  1004. # 1999 only. In the year 2000, the change to daylight savings time was
  1005. # similar to 1999, but although the change back will be on a Friday, it
  1006. # will take place from 1 a.m. IDT to midnight IST. Starting in 2001, all
  1007. # changes to/from will take place at 1 a.m. old time, but now there is no
  1008. # rule as to what day of the week it will take place in as the start date
  1009. # (except in 2003) is the night after the Passover Seder (i.e. the eve

  1838. # Palestine
  1839. # From Amos Shapir (1998-02-15):
  1840. #
  1841. # From 1917 until 1948-05-15, all of Palestine, including the parts now
  1842. # known as the Gaza Strip and the West Bank, was under British rule.
  1843. # Therefore the rules given for Israel for that period, apply there too...
  1844. #
  1845. # The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
  1846. # (except a short occupation by Israel from 1956-11 till 1957-03, but no
  1847. # time zone was affected then). It was never formally annexed to Egypt,
  1848. # though.
  1849. #
  1850. # The rest of Palestine was under Jordanian rule at that time, formally
  1851. # annexed in 1950 as the West Bank (and the word "Trans" was dropped from
  1852. # the country's previous name of "the Hashemite Kingdom of the
  1853. # Trans-Jordan"). So the rules for Jordan for that time apply. Major
  1854. # towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
  1855. # East Jerusalem.
  1856. #
  1857. # Both areas were occupied by Israel in June 1967, but not annexed (except
  1858. # for East Jerusalem). They were on Israel time since then; there might
  1859. # have been a Military Governor's order about time zones, but I'm not aware
  1860. # of any (such orders may have been issued semi-annually whenever summer
  1861. # time was in effect, but maybe the legal aspect of time was just neglected).
  1862. #
  1863. # The Palestinian Authority was established in 1993, and got hold of most
  1864. # towns in the West Bank and Gaza by 1995. I know that in order to
  1865. # demonstrate...independence, they have been switching to
  1866. # summer time and back on a different schedule than Israel's, but I don't
  1867. # know when this was started, or what algorithm is used (most likely the
  1868. # Jordanian one).
  1869. #
  1870. # To summarize, the table should probably look something like that:
  1871. #
  1872. # Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-
  1873. # ------------+-----------+-----------+-----------+-----------
  1874. # Israel | Zion | Zion | Zion | Zion
  1875. # West bank | Zion | Jordan | Zion | Jordan
  1876. # Gaza | Zion | Egypt | Zion | Jordan
  1877. #
  1878. # I guess more info may be available from the PA's web page (if/when they
  1879. # have one).
  1880. # From Paul Eggert (2006-03-22):
  1881. # Shanks & Pottenger write that Gaza did not observe DST until 1957, but go
  1882. # with Shapir and assume that it observed DST from 1940 through 1947,
  1883. # and that it used Jordanian rules starting in 1996.
  1884. # We don't yet need a separate entry for the West Bank, since
  1885. # the only differences between it and Gaza that we know about
  1886. # occurred before our cutoff date of 1970.
  1887. # However, as we get more information, we may need to add entries
  1888. # for parts of the West Bank as they transitioned from Israel's rules
  1889. # to Palestine's rules.
  1890. # From IINS News Service - Israel - 1998-03-23 10:38:07 Israel time,
  1891. # forwarded by Ephraim Silverberg:
  1892. #
  1893. # Despite the fact that Israel changed over to daylight savings time
  1894. # last week, the PLO Authority (PA) has decided not to turn its clocks
  1895. # one-hour forward at this time. As a sign of independence from Israeli rule,
  1896. # the PA has decided to implement DST in April.

  2227. # People who live in regions under Tamil control can use [TZ='Asia/Kolkata'],
  2228. # as that zone has agreed with the Tamil areas since our cutoff date of 1970.
  2229. # From K Sethu (2006-04-25):
  2230. # I think the abbreviation LKT originated from the world of computers at
  2231. # the time of or subsequent to the time zone changes by SL Government
  2232. # twice in 1996 and probably SL Government or its standardization
  2233. # agencies never declared an abbreviation as a national standard.
  2234. #
  2235. # I recollect before the recent change the government annoucemments
  2236. # mentioning it as simply changing Sri Lanka Standard Time or Sri Lanka
  2237. # Time and no mention was made about the abbreviation.
  2238. #
  2239. # If we look at Sri Lanka Department of Government's "Official News
  2240. # Website of Sri Lanka" ... http://www.news.lk/ we can see that they
  2241. # use SLT as abbreviation in time stamp at the beginning of each news
  2242. # item....
  2243. #
  2244. # Within Sri Lanka I think LKT is well known among computer users and
  2245. # adminsitrators. In my opinion SLT may not be a good choice because the
  2246. # nation's largest telcom / internet operator Sri Lanka Telcom is well
  2247. # known by that abbreviation - simply as SLT (there IP domains are
  2248. # slt.lk and sltnet.lk).
  2249. #
  2250. # But if indeed our government has adopted SLT as standard abbreviation
  2251. # (that we have not known so far) then it is better that it be used for

  2353. # Ministry of Electricity to begin daylight savings time on Friday April
  2354. # 4th, advancing clocks one hour ahead on midnight of Thursday April 3rd."
  2355. # Since Syria is two hours east of UTC, the 2200 and 2100 transition times
  2356. # shown above match up with midnight in Syria.
  2357. # From Arthur David Olson (2008-03-18):
  2358. # My buest guess at a Syrian rule is "the Friday nearest April 1";
  2359. # coding that involves either using a "Mar Fri>=29" construct that old time zone
  2360. # compilers can't handle or having multiple Rules (a la Israel).
  2361. # For now, use "Apr Fri>=1", and go with IATA on a uniform Sep 30 end.

  2363. # Syria has now officially decided to end DST on 2008-11-01 this year,
  2364. # according to the following article in the Syrian Arab News Agency (SANA).
  2365. #
  2366. # The article is in Arabic, and seems to tell that they will go back to
  2367. # winter time on 2008-11-01 at 00:00 local daylight time (delaying/setting
  2368. # clocks back 60 minutes).
