| 10 | # From Paul Eggert (2006-03-22): |
| 11 | # |
| 12 | # A good source for time zone historical data outside the U.S. is |
| 13 | # Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition), |
| 14 | # San Diego: ACS Publications, Inc. (2003). |
| 15 | # |
| 16 | # Gwillim Law writes that a good source |
| 17 | # for recent time zone data is the International Air Transport |
| 18 | # Association's Standard Schedules Information Manual (IATA SSIM), |
| 19 | # published semiannually. Law sent in several helpful summaries |
| 20 | # of the IATA's data after 1990. |
| 21 | # |
| 22 | # Except where otherwise noted, Shanks & Pottenger is the source for |
| 23 | # entries through 1990, and IATA SSIM is the source for entries afterwards. |
| 24 | # |
| 25 | # Another source occasionally used is Edward W. Whitman, World Time Differences, |
| 26 | # Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which |
| 27 | # I found in the UCLA library. |
| 28 | # |
| 29 | # A reliable and entertaining source about time zones is |

| 228 | |
| 229 | # From Bob Devine (1988-01-28): |
| 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 |
| 234 | # the Xinjiang Uyghur Autonomous Region). I don't know about DST for it. |
| 235 | # |
| 236 | # . . .I just deleted the DST table and this editor makes it too |

| 271 | # http://www.astro.com/atlas site [with provinces and county |
| 272 | # boundaries summarized below].... A few other exceptions were two |
| 273 | # counties on the Sichuan side of the Xizang-Sichuan border, |
| 274 | # counties Dege and Baiyu which lies on the Sichuan side and are |
| 275 | # therefore supposed to be GMT+7, Xizang region being GMT+6, but Dege |
| 276 | # county is GMT+8 according to astro.com while Baiyu county is GMT+6 |
| 277 | # (could be true), for the moment I am assuming that those two |
| 278 | # counties are mistakes in the astro.com data. |
| 279 | |
| 280 | # From Paul Eggert (2008-02-11): |
| 281 | # I just now checked Google News for western news sources that talk |
| 282 | # about China's single time zone, and couldn't find anything before 1986 |
| 283 | # talking about China being in one time zone. (That article was: Jim |
| 284 | # Mann, "A clumsy embrace for another western custom: China on daylight |
| 285 | # time--sort of", Los Angeles Times, 1986-05-05. By the way, this |
| 286 | # article confirms the tz database's data claiming that China began |

| 289 | # From Thomas S. Mullaney (2008-02-11): |
| 290 | # I think you're combining two subjects that need to treated |
| 291 | # separately: daylight savings (which, you're correct, wasn't |
| 292 | # implemented until the 1980s) and the unified time zone centered near |
| 293 | # Beijing (which was implemented in 1949). Briefly, there was also a |
| 294 | # "Lhasa Time" in Tibet and "Urumqi Time" in Xinjiang. The first was |
| 295 | # ceased, and the second eventually recognized (again, in the 1980s). |
| 296 | # |
| 297 | # From Paul Eggert (2008-06-30): |
| 298 | # There seems to be a good chance China switched to a single time zone in 1949 |

| 439 | # From Paul Eggert (1994-11-19): |

| 441 | # an hour recently, due to a law proposed by Zurab Murvanidze, |
| 442 | # an MP who went on a hunger strike for 11 days to force discussion about it! |
| 443 | # We have no details, but we'll guess they didn't move the clocks back in fall. |

| 445 | # From Mathew Englander, quoting AP (1996-10-23 13:05-04): |
| 446 | # Instead of putting back clocks at the end of October, Georgia |
| 447 | # will stay on daylight savings time this winter to save energy, |
| 448 | # President Eduard Shevardnadze decreed Wednesday. |
| 449 | # |
| 450 | # From the BBC via Joseph S. Myers (2004-06-27): |
| 451 | # |
| 452 | # Georgia moved closer to Western Europe on Sunday... The former Soviet |
| 453 | # republic has changed its time zone back to that of Moscow. As a result it |
| 454 | # is now just four hours ahead of Greenwich Mean Time, rather than five hours |
| 455 | # ahead. The switch was decreed by the pro-Western president of Georgia, |
| 456 | # Mikhail Saakashvili, who said the change was partly prompted by the process |
| 457 | # of integration into Europe. |
| 458 | |
| 459 | # From Teimuraz Abashidze (2005-11-07): |
| 460 | # Government of Georgia ... decided to NOT CHANGE daylight savings time on |
| 461 | # [Oct.] 30, as it was done before during last more than 10 years. |
| 462 | # Currently, we are in fact GMT +4:00, as before 30 October it was GMT |

| 464 | # about it. As far as I can find, I was told, that there is no document, |

| 592 | # |

| 594 | # based on the suggestion number 2221/D dated 1370/4/22 [1991-07-13] |
| 595 | # of the Country's Organization for Official and Employment Affairs, |
| 596 | # and referring to the law for equating the working hours of workers |
| 597 | # and officers in the whole country dated 1359/4/23 [1980-07-14], and |
| 598 | # for synchronizing the official times of the country, agreed that: |
| 599 | # |
| 600 | # The official time of the country will should move forward one hour |
| 601 | # at the 24[:00] hours of the first day of Farvardin and should return |
| 602 | # to its previous state at the 24[:00] hours of the 30th day of |
| 603 | # Shahrivar. |
| 604 | # |
| 605 | # First Deputy to the President - Hassan Habibi |
| 606 | # |
| 607 | # From personal experience, that agrees with what has been followed |
| 608 | # for at least the last 5 years. Before that, for a few years, the |
| 609 | # date used was the first Thursday night of Farvardin and the last |
| 610 | # Thursday night of Shahrivar, but I can't give exact dates.... |
| 611 | # I have also changed the abbreviations to what is considered correct |
| 612 | # here in Iran, IRST for regular time and IRDT for daylight saving time. |
| 613 | # |
| 614 | # From Roozbeh Pournader (2005-04-05): |
| 615 | # The text of the Iranian law, in effect since 1925, clearly mentions |
| 616 | # that the true solar year is the measure, and there is no arithmetic |
| 617 | # leap year calculation involved. There has never been any serious |
| 618 | # plan to change that law.... |
| 619 | # |
| 620 | # From Paul Eggert (2006-03-22): |
| 621 | # Go with Shanks & Pottenger before Sept. 1991, and with Pournader thereafter. |
| 622 | # I used Ed Reingold's cal-persia in GNU Emacs 21.2 to check Persian dates, |
| 623 | # stopping after 2037 when 32-bit time_t's overflow. |
| 624 | # That cal-persia used Birashk's approximation, which disagrees with the solar |
| 625 | # calendar predictions for the year 2025, so I corrected those dates by hand. |
| 626 | # |
| 627 | # From Oscar van Vlijmen (2005-03-30), writing about future |
| 628 | # discrepancies between cal-persia and the Iranian calendar: |
| 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 |
| 638 | # Reingold's/Dershowitz' calculator gives correctly the Gregorian date |
| 639 | # 2058-03-21 for 1 Farvardin 1437 (astronomical). |

| 719 | # From Jonathan Lennox (2000-06-12): |
| 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). |

| 835 | # (1997-03-04, 1998-03-16, 1998-12-28, 2000-01-17, 2000-07-25, 2004-12-22, |
| 836 | # and 2005-02-17): |
| 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). |

| 1021 | # Occupation authorities imposed daylight-saving time on Japan on |

| 1023 | # daylight-saving time just three days after the bill was passed generated |
| 1024 | # deep hatred of the concept.... The Diet unceremoniously passed a bill to |
| 1025 | # dump the unpopular system in October 1951, less than a month after the San |
| 1026 | # Francisco Peace Treaty was signed. (A government poll in 1951 showed 53% |
| 1027 | # of the Japanese wanted to scrap daylight-saving time, as opposed to 30% who |

| 1414 | |
| 1415 | # From Oscar van Vlijmen (1999-12-11): |
| 1416 | # <a href="http://www.mongoliatourism.gov.mn/general.htm"> |
| 1417 | # General Information Mongolia |
| 1418 | # </a> (1999-09) |
| 1419 | # "Time: Mongolia has two time zones. Three westernmost provinces of |
| 1420 | # Bayan-Ulgii, Uvs, and Hovd are one hour earlier than the capital city, and |
| 1421 | # the rest of the country follows the Ulaanbaatar time, which is UTC/GMT plus |
| 1422 | # eight hours." |
| 1423 | |
| 1424 | # From Rives McDow (1999-12-13): |
| 1425 | # Mongolia discontinued the use of daylight savings time in 1999; 1998 |
| 1426 | # being the last year it was implemented. The dates of implementation I am |
| 1427 | # unsure of, but most probably it was similar to Russia, except for the time |
| 1428 | # of implementation may have been different.... |
| 1429 | # Some maps in the past have indicated that there was an additional time |
| 1430 | # zone in the eastern part of Mongolia, including the provinces of Dornod, |
| 1431 | # Suhbaatar, and possibly Khentij. |
| 1432 | |
| 1433 | # From Paul Eggert (1999-12-15): |
| 1434 | # Naming and spelling is tricky in Mongolia. |
| 1435 | # We'll use Hovd (also spelled Chovd and Khovd) to represent the west zone; |
| 1436 | # the capital of the Hovd province is sometimes called Hovd, sometimes Dund-Us, |
| 1437 | # and sometimes Jirgalanta (with variant spellings), but the name Hovd |
| 1438 | # is good enough for our purposes. |
| 1439 | |
| 1440 | # From Rives McDow (2001-05-13): |
| 1441 | # In addition to Mongolia starting daylight savings as reported earlier |
| 1442 | # (adopted DST on 2001-04-27 02:00 local time, ending 2001-09-28), |
| 1443 | # there are three time zones. |

| 1449 | # |
| 1450 | # [The province of Selenge is omitted from the above lists.] |
| 1451 | |
| 1452 | # From Ganbold Ts., Ulaanbaatar (2004-04-17): |

| 1454 | # It will change back to normal at 02:00 local time last Saturday of |
| 1455 | # September.... As I remember this rule was changed in 2001. |
| 1456 | # |
| 1457 | # From Paul Eggert (2004-04-17): |
| 1458 | # For now, assume Rives McDow's informant got confused about Friday vs |
| 1459 | # Saturday, and that his 2001 dates should have 1 added to them. |
| 1460 | |
| 1461 | # From Paul Eggert (2005-07-26): |

| 1463 | # Bill Bonnet (2005-05-19) reports that the US Embassy in Ulaanbaatar says |
| 1464 | # there is only one time zone and that DST is observed, citing Microsoft |
| 1465 | # Windows XP as the source. Risto Nykanen (2005-05-16) reports that |
| 1466 | # travelmongolia.org says there are two time zones (UTC+7, UTC+8) with no DST. |

| 1472 | # (2005-03-31 06:05 +0700) saying "Mongolia actually has 3.5 time zones. |
| 1473 | # The West (OLGII) is +7 GMT, most of the country is ULAT is +8 GMT |
| 1474 | # and some Eastern provinces are +9 GMT but Sukhbaatar Aimag is SUHK +8.5 GMT. |
| 1475 | # The SUKH timezone is new this year, it is one of the few things the |

| 1689 | |
| 1690 | # From Amos Shapir (1998-02-15): |
| 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 |
| 1716 | # demonstrate...independence, they have been switching to |
| 1717 | # summer time and back on a different schedule than Israel's, but I don't |
| 1718 | # know when this was started, or what algorithm is used (most likely the |
| 1719 | # Jordanian one). |
| 1720 | # |
| 1721 | # To summarize, the table should probably look something like that: |
| 1722 | # |
| 1723 | # Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996- |

| 1728 | # |
| 1729 | # I guess more info may be available from the PA's web page (if/when they |
| 1730 | # have one). |
| 1731 | |
| 1732 | # From Paul Eggert (2006-03-22): |
| 1733 | # Shanks & Pottenger write that Gaza did not observe DST until 1957, but go |
| 1734 | # with Shapir and assume that it observed DST from 1940 through 1947, |
| 1735 | # and that it used Jordanian rules starting in 1996. |
| 1736 | # We don't yet need a separate entry for the West Bank, since |
| 1737 | # the only differences between it and Gaza that we know about |
| 1738 | # occurred before our cutoff date of 1970. |
| 1739 | # However, as we get more information, we may need to add entries |
| 1740 | # for parts of the West Bank as they transitioned from Israel's rules |
| 1741 | # to Palestine's rules. If you have more info about this, please |
| 1742 | # send it to tz@elsie.nci.nih.gov for incorporation into future editions. |

| 1745 | # forwarded by Ephraim Silverberg: |
| 1746 | # |
| 1747 | # Despite the fact that Israel changed over to daylight savings time |
| 1748 | # last week, the PLO Authority (PA) has decided not to turn its clocks |
| 1749 | # one-hour forward at this time. As a sign of independence from Israeli rule, |
| 1750 | # the PA has decided to implement DST in April. |

| 1757 | # the Palestinian National Authority changed to DST on 1999-04-15. |
| 1758 | # I vaguely recall that they switch back in October (sorry, forgot the source). |
| 1759 | # For now, let's assume that the spring switch was at 24:00, |

| 1765 | # From Steffen Thorsen (2005-11-23): |
| 1766 | # A user from Gaza reported that Gaza made the change early because of |

| 1768 | # there is a good chance next year's end date will be around two weeks |
| 1769 | # earlier--the same goes for Jordan. |
| 1770 | |
| 1771 | # From Steffen Thorsen (2006-08-17): |
| 1772 | # I was informed by a user in Bethlehem that in Bethlehem it started the |
| 1773 | # same day as Israel, and after checking with other users in the area, I |
| 1774 | # was informed that they started DST one day after Israel. I was not |
| 1775 | # able to find any authoritative sources at the time, nor details if |
| 1776 | # Gaza changed as well, but presumed Gaza to follow the same rules as |
| 1777 | # the West Bank. |

| 1785 | # I guess it is likely that next year's date will be moved as well, |

| 1791 | |
| 1792 | # From Paul Eggert (2007-09-20): |
| 1793 | # My understanding is that Gaza and the West Bank disagree even over when |

| 1943 | # <http://news.sinhalaya.com/wmview.php?ArtID=11002> (2006-04-13): |
| 1944 | # 0030 hrs on April 15, 2006 (midnight of April 14, 2006 +30 minutes) |

| 1949 | # [The Tamil Tigers] never accepted the original 1996 time change and simply |
| 1950 | # kept their clocks set five and a half hours ahead of Greenwich Mean |
| 1951 | # Time (GMT), in line with neighbor India. |
| 1952 | # From Paul Eggert (2006-04-18): |
| 1953 | # People who live in regions under Tamil control can use [TZ='Asia/Kolkata'], |
| 1954 | # as that zone has agreed with the Tamil areas since our cutoff date of 1970. |
| 1955 | |
| 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 |
| 1978 | # (that we have not known so far) then it is better that it be used for |
| 1979 | # all computers. |
| 1980 | |
| 1981 | # From Paul Eggert (2006-04-25): |
| 1982 | # One possibility is that we wait for a bit for the dust to settle down |
| 1983 | # and then see what people actually say in practice. |
