  399. # an hour recently, due to a law proposed by Zurab Murvanidze,
  400. # an MP who went on a hunger strike for 11 days to force discussion about it!
  401. # We have no details, but we'll guess they didn't move the clocks back in fall.
  402. #
  403. # From Mathew Englander, quoting AP (1996-10-23 13:05-04):
  404. # Instead of putting back clocks at the end of October, Georgia
  405. # will stay on daylight savings time this winter to save energy,
  406. # President Eduard Shevardnadze decreed Wednesday.
  407. #
  408. # From the BBC via Joseph S. Myers (2004-06-27):
  409. #
  410. # Georgia moved closer to Western Europe on Sunday... The former Soviet
  411. # republic has changed its time zone back to that of Moscow. As a result it
  412. # is now just four hours ahead of Greenwich Mean Time, rather than five hours
  413. # ahead. The switch was decreed by the pro-Western president of Georgia,
  414. # Mikhail Saakashvili, who said the change was partly prompted by the process
  415. # of integration into Europe.
  416. # From Teimuraz Abashidze (2005-11-07):
  417. # Government of Georgia ... decided to NOT CHANGE daylight savings time on
  418. # [Oct.] 30, as it was done before during last more than 10 years.
  419. # Currently, we are in fact GMT +4:00, as before 30 October it was GMT

  421. # about it. As far as I can find, I was told, that there is no document,
  422. # because we just DIDN'T ISSUE document about switching to winter time....

  531. # The Gregorian dates in brackets are mine:
  532. #
  533. # Official Newspaper No. 13548-1370/6/25 [1991-09-16]

  536. # The Rule About Change of the Official Time of the Country
  537. #
  538. # The Board of Ministers, in the meeting dated 1370/5/23 [1991-08-14],
  539. # based on the suggestion number 2221/D dated 1370/4/22 [1991-07-13]
  540. # of the Country's Organization for Official and Employment Affairs,
  541. # and referring to the law for equating the working hours of workers
  542. # and officers in the whole country dated 1359/4/23 [1980-07-14], and
  543. # for synchronizing the official times of the country, agreed that:
  544. #
  545. # The official time of the country will should move forward one hour
  546. # at the 24[:00] hours of the first day of Farvardin and should return
  547. # to its previous state at the 24[:00] hours of the 30th day of

  549. #
  550. # First Deputy to the President - Hassan Habibi
  551. #
  552. # From personal experience, that agrees with what has been followed
  553. # for at least the last 5 years. Before that, for a few years, the
  554. # date used was the first Thursday night of Farvardin and the last
  555. # Thursday night of Shahrivar, but I can't give exact dates....
  556. # I have also changed the abbreviations to what is considered correct
  557. # here in Iran, IRST for regular time and IRDT for daylight saving time.
  558. #
  559. # From Roozbeh Pournader (2005-04-05):
  560. # The text of the Iranian law, in effect since 1925, clearly mentions
  561. # that the true solar year is the measure, and there is no arithmetic
  562. # leap year calculation involved. There has never been any serious
  563. # plan to change that law....
  564. #
  565. # From Paul Eggert (2006-03-22):
  566. # Go with Shanks & Pottenger before Sept. 1991, and with Pournader thereafter.
  567. # I used Ed Reingold's cal-persia in GNU Emacs 21.2 to check Persian dates,
  568. # stopping after 2037 when 32-bit time_t's overflow.
  569. # That cal-persia used Birashk's approximation, which disagrees with the solar
  570. # calendar predictions for the year 2025, so I corrected those dates by hand.
  571. #
  572. # From Oscar van Vlijmen (2005-03-30), writing about future
  573. # discrepancies between cal-persia and the Iranian calendar:
  574. # For 2091 solar-longitude-after yields 2091-03-20 08:40:07.7 UT for
  575. # the vernal equinox and that gets so close to 12:00 some local
  576. # Iranian time that the definition of the correct location needs to be
  577. # known exactly, amongst other factors. 2157 is even closer:
  578. # 2157-03-20 08:37:15.5 UT. But the Gregorian year 2025 should give
  579. # no interpretation problem whatsoever. By the way, another instant
  580. # in the near future where there will be a discrepancy between
  581. # arithmetical and astronomical Iranian calendars will be in 2058:
  582. # vernal equinox on 2058-03-20 09:03:05.9 UT. The Java version of
  583. # Reingold's/Dershowitz' calculator gives correctly the Gregorian date
  584. # 2058-03-21 for 1 Farvardin 1437 (astronomical).

  663. # An article in this week's Economist ("Inside the Saddam-free zone", p. 50 in
  664. # the U.S. edition) on the Iraqi Kurds contains a paragraph:
  665. # "The three northern provinces ... switched their clocks this spring and
  666. # are an hour ahead of Baghdad."
  667. #
  668. # But Rives McDow (2000-06-18) quotes a contact in Iraqi-Kurdistan as follows:
  669. # In the past, some Kurdish nationalists, as a protest to the Iraqi
  670. # Government, did not adhere to daylight saving time. They referred
  671. # to daylight saving as Saddam time. But, as of today, the time zone
  672. # in Iraqi-Kurdistan is on standard time with Baghdad, Iraq.

  708. # From Ephraim Silverberg (2001-01-11):
  709. #
  710. # I coined "IST/IDT" circa 1988. Until then there were three
  711. # different abbreviations in use:
  712. #
  713. # JST Jerusalem Standard Time [Danny Braniss, Hebrew University]
  714. # IZT Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
  715. # EEST Eastern Europe Standard Time [used by almost everyone else]
  716. #
  717. # Since timezones should be called by country and not capital cities,
  718. # I ruled out JST. As Israel is in Asia Minor and not Eastern Europe,
  719. # EEST was equally unacceptable. Since "zonal" was not compatible with
  720. # any other timezone abbreviation, I felt that 'IST' was the way to go
  721. # and, indeed, it has received almost universal acceptance in timezone
  722. # settings in Israeli computers.
  723. #
  724. # In any case, I am happy to share timezone abbreviations with India,
  725. # high on my favorite-country list (and not only because my wife's
  726. # family is from India).

  771. # and 2005-02-17):
  772. # According to the Office of the Secretary General of the Ministry of
  773. # Interior, there is NO set rule for Daylight-Savings/Standard time changes.
  774. # One thing is entrenched in law, however: that there must be at least 150
  775. # days of daylight savings time annually. From 1993-1998, the change to
  776. # daylight savings time was on a Friday morning from midnight IST to
  777. # 1 a.m IDT; up until 1998, the change back to standard time was on a
  778. # Saturday night from midnight daylight savings time to 11 p.m. standard
  779. # time. 1996 is an exception to this rule where the change back to standard
  780. # time took place on Sunday night instead of Saturday night to avoid
  781. # conflicts with the Jewish New Year. In 1999, the change to
  782. # daylight savings time was still on a Friday morning but from
  783. # 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
  784. # was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for
  785. # 1999 only. In the year 2000, the change to daylight savings time was
  786. # similar to 1999, but although the change back will be on a Friday, it
  787. # will take place from 1 a.m. IDT to midnight IST. Starting in 2001, all
  788. # changes to/from will take place at 1 a.m. old time, but now there is no
  789. # rule as to what day of the week it will take place in as the start date
  790. # (except in 2003) is the night after the Passover Seder (i.e. the eve
  791. # of the 16th of Nisan in the lunar Hebrew calendar) and the end date
  792. # (except in 2002) is three nights before Yom Kippur [Day of Atonement]

  1546. # From Amos Shapir (1998-02-15):
  1547. #
  1548. # From 1917 until 1948-05-15, all of Palestine, including the parts now
  1549. # known as the Gaza Strip and the West Bank, was under British rule.
  1550. # Therefore the rules given for Israel for that period, apply there too...
  1551. #
  1552. # The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
  1553. # (except a short occupation by Israel from 1956-11 till 1957-03, but no
  1554. # time zone was affected then). It was never formally annexed to Egypt,
  1555. # though.
  1556. #
  1557. # The rest of Palestine was under Jordanian rule at that time, formally
  1558. # annexed in 1950 as the West Bank (and the word "Trans" was dropped from
  1559. # the country's previous name of "the Hashemite Kingdom of the
  1560. # Trans-Jordan"). So the rules for Jordan for that time apply. Major
  1561. # towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
  1562. # East Jerusalem.
  1563. #
  1564. # Both areas were occupied by Israel in June 1967, but not annexed (except
  1565. # for East Jerusalem). They were on Israel time since then; there might
  1566. # have been a Military Governor's order about time zones, but I'm not aware
  1567. # of any (such orders may have been issued semi-annually whenever summer
  1568. # time was in effect, but maybe the legal aspect of time was just neglected).
  1569. #
  1570. # The Palestinian Authority was established in 1993, and got hold of most
  1571. # towns in the West Bank and Gaza by 1995. I know that in order to
  1572. # demonstrate...independence, they have been switching to
  1573. # summer time and back on a different schedule than Israel's, but I don't
  1574. # know when this was started, or what algorithm is used (most likely the
  1575. # Jordanian one).
  1576. #
  1577. # To summarize, the table should probably look something like that:
  1578. #
  1579. # Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-

  1585. # I guess more info may be available from the PA's web page (if/when they

  1589. # with Shapir and assume that it observed DST from 1940 through 1947,
  1590. # and that it used Jordanian rules starting in 1996.
  1591. # We don't yet need a separate entry for the West Bank, since
  1592. # the only differences between it and Gaza that we know about
  1593. # occurred before our cutoff date of 1970.
  1594. # However, as we get more information, we may need to add entries
  1595. # for parts of the West Bank as they transitioned from Israel's rules

  1610. # the Palestinian National Authority changed to DST on 1999-04-15.
  1611. # I vaguely recall that they switch back in October (sorry, forgot the source).
  1612. # For now, let's assume that the spring switch was at 24:00,
  1613. # and that they switch at 0:00 on the 3rd Fridays of April and October.
  1614. # From Paul Eggert (2005-11-22):
  1615. # Starting 2004 transitions are from Steffen Thorsen's web site timeanddate.com.
  1616. # From Steffen Thorsen (2005-11-23):
  1617. # A user from Gaza reported that Gaza made the change early because of
  1618. # the Ramadan. Next year Ramadan will be even earlier, so I think
  1619. # there is a good chance next year's end date will be around two weeks
  1620. # earlier--the same goes for Jordan.
  1621. # From Steffen Thorsen (2006-08-17):
  1622. # I was informed by a user in Bethlehem that in Bethlehem it started the
  1623. # same day as Israel, and after checking with other users in the area, I
  1624. # was informed that they started DST one day after Israel. I was not
  1625. # able to find any authoritative sources at the time, nor details if
  1626. # Gaza changed as well, but presumed Gaza to follow the same rules as
  1627. # the West Bank.
  1628. # From Steffen Thorsen (2006-09-26):
  1629. # according to the Palestine News Network (2006-09-19):
  1630. # http://english.pnn.ps/index.php?option=com_content&task=view&id=596&Itemid=5
  1631. # > The Council of Ministers announced that this year its winter schedule
  1632. # > will begin early, as of midnight Thursday. It is also time to turn
  1633. # > back the clocks for winter. Friday will begin an hour late this week.
  1634. # I guess it is likely that next year's date will be moved as well,
  1635. # because of the Ramadan.
  1636. # From Jesper Norgaard Welen (2007-09-18):
  1637. # According to Steffen Thorsen's web site the Gaza Strip and the rest of the
  1638. # Palestinian territories left DST early on 13.th. of September at 2:00.
  1639. # From Paul Eggert (2007-09-20):
  1640. # My understanding is that Gaza and the West Bank disagree even over when
  1641. # the weekend is (Thursday+Friday versus Friday+Saturday), so I'd be a bit
  1642. # surprised if they agreed about DST. But for now, assume they agree.
  1643. # For lack of better information, predict that future changes will be
  1644. # the 2nd Thursday of September at 02:00.
  1645. # From Alexander Krivenyshev (2008-08-28):
  1646. # Here is an article, that Mideast running on different clocks at Ramadan.
  1647. #
  1648. # Gaza Strip (as Egypt) ended DST at midnight Thursday (Aug 28, 2008), while
  1649. # the West Bank will end Daylight Saving Time at midnight Sunday (Aug 31, 2008).

  1784. # People who live in regions under Tamil control can use [TZ='Asia/Kolkata'],

  1787. # I think the abbreviation LKT originated from the world of computers at
  1788. # the time of or subsequent to the time zone changes by SL Government
  1789. # twice in 1996 and probably SL Government or its standardization
  1790. # agencies never declared an abbreviation as a national standard.

  1792. # I recollect before the recent change the government annoucemments
  1793. # mentioning it as simply changing Sri Lanka Standard Time or Sri Lanka
  1794. # Time and no mention was made about the abbreviation.
  1795. #
  1796. # If we look at Sri Lanka Department of Government's "Official News
  1797. # Website of Sri Lanka" ... http://www.news.lk/ we can see that they
  1798. # use SLT as abbreviation in time stamp at the beginning of each news
  1799. # item....
  1800. #
  1801. # Within Sri Lanka I think LKT is well known among computer users and
  1802. # adminsitrators. In my opinion SLT may not be a good choice because the
  1803. # nation's largest telcom / internet operator Sri Lanka Telcom is well
  1804. # known by that abbreviation - simply as SLT (there IP domains are

  1806. #
  1807. # But if indeed our government has adopted SLT as standard abbreviation
  1808. # (that we have not known so far) then it is better that it be used for

  1911. # 4th, advancing clocks one hour ahead on midnight of Thursday April 3rd."
  1912. # Since Syria is two hours east of UTC, the 2200 and 2100 transition times
  1913. # shown above match up with midnight in Syria.
  1914. # From Arthur David Olson (2008-03-18):
  1915. # My buest guess at a Syrian rule is "the Friday nearest April 1";

  1917. # compilers can't handle or having multiple Rules (a la Israel).
  1918. # For now, use "Apr Fri>=1", and go with IATA on a uniform Sep 30 end.
