| 30 | # From Paul Eggert (2006-03-22): |
| 31 | # |
| 32 | # A good source for time zone historical data outside the U.S. is |
| 33 | # Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition), |
| 34 | # San Diego: ACS Publications, Inc. (2003). |
| 35 | # |
| 36 | # Gwillim Law writes that a good source |
| 37 | # for recent time zone data is the International Air Transport |
| 38 | # Association's Standard Schedules Information Manual (IATA SSIM), |
| 39 | # published semiannually. Law sent in several helpful summaries |
| 40 | # of the IATA's data after 1990. |
| 41 | # |
| 42 | # Except where otherwise noted, Shanks & Pottenger is the source for |
| 43 | # entries through 1990, and IATA SSIM is the source for entries afterwards. |
| 44 | # |
| 45 | # Another source occasionally used is Edward W. Whitman, World Time Differences, |
| 46 | # Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which |
| 47 | # I found in the UCLA library. |
| 48 | # |
| 49 | # A reliable and entertaining source about time zones is |
| 50 | # Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997). |

| 204 | # No they don't. See TIME mag, 1986-02-17 p.52. Even though |
| 205 | # China is across 4 physical time zones, before Feb 1, 1986 only the |
| 206 | # Peking (Bejing) time zone was recognized. Since that date, China |
| 207 | # has two of 'em -- Peking's and Urumqi (named after the capital of |
| 208 | # the Xinjiang Uyghur Autonomous Region). I don't know about DST for it. |
| 209 | # |

| 391 | # From Paul Eggert (1994-11-19): |
| 392 | # Today's _Economist_ (p 60) reports that Georgia moved its clocks forward |
| 393 | # an hour recently, due to a law proposed by Zurab Murvanidze, |
| 394 | # an MP who went on a hunger strike for 11 days to force discussion about it! |
| 395 | # We have no details, but we'll guess they didn't move the clocks back in fall. |
| 396 | # |
| 397 | # From Mathew Englander, quoting AP (1996-10-23 13:05-04): |
| 398 | # Instead of putting back clocks at the end of October, Georgia |
| 399 | # will stay on daylight savings time this winter to save energy, |
| 400 | # President Eduard Shevardnadze decreed Wednesday. |
| 401 | # |
| 402 | # From the BBC via Joseph S. Myers (2004-06-27): |
| 403 | # |
| 404 | # Georgia moved closer to Western Europe on Sunday... The former Soviet |
| 405 | # republic has changed its time zone back to that of Moscow. As a result it |
| 406 | # is now just four hours ahead of Greenwich Mean Time, rather than five hours |
| 407 | # ahead. The switch was decreed by the pro-Western president of Georgia, |
| 408 | # Mikhail Saakashvili, who said the change was partly prompted by the process |
| 409 | # of integration into Europe. |
| 410 | |
| 411 | # From Teimuraz Abashidze (2005-11-07): |
| 412 | # Government of Georgia ... decided to NOT CHANGE daylight savings time on |
| 413 | # [Oct.] 30, as it was done before during last more than 10 years. |
| 414 | # Currently, we are in fact GMT +4:00, as before 30 October it was GMT |
| 415 | # +3:00.... The problem is, there is NO FORMAL LAW or governmental document |
| 416 | # about it. As far as I can find, I was told, that there is no document, |
| 417 | # because we just DIDN'T ISSUE document about switching to winter time.... |
| 418 | # I don't know what can be done, especially knowing that some years ago our |
| 419 | # DST rules where changed THREE TIMES during one month. |

| 442 | # East Timor may be late for its millennium |
| 443 | # </a> (1999-12-26/31): |
| 444 | # Portugal tried to change the time forward in 1974 because the sun |

| 486 | # says that Indonesia's time zones changed on 1988-01-01. Looking at some |

| 490 | # From Paul Eggert (2007-03-10): |

| 492 | # JohnTWB writes that Japanese forces did not surrender control in |
| 493 | # Indonesia until 1945-09-01 00:00 at the earliest (in Jakarta) and |

| 536 | # From Roozbeh Pournader (2003-03-15): |
| 537 | # This is an English translation of what I just found (originally in Persian). |
| 538 | # The Gregorian dates in brackets are mine: |
| 539 | # |
| 540 | # Official Newspaper No. 13548-1370/6/25 [1991-09-16] |
| 541 | # No. 16760/T233 H 1370/6/10 [1991-09-01] |

| 543 | # The Rule About Change of the Official Time of the Country |
| 544 | # |
| 545 | # The Board of Ministers, in the meeting dated 1370/5/23 [1991-08-14], |
| 546 | # based on the suggestion number 2221/D dated 1370/4/22 [1991-07-13] |
| 547 | # of the Country's Organization for Official and Employment Affairs, |
| 548 | # and referring to the law for equating the working hours of workers |
| 549 | # and officers in the whole country dated 1359/4/23 [1980-07-14], and |
| 550 | # for synchronizing the official times of the country, agreed that: |
| 551 | # |
| 552 | # The official time of the country will should move forward one hour |
| 553 | # at the 24[:00] hours of the first day of Farvardin and should return |
| 554 | # to its previous state at the 24[:00] hours of the 30th day of |
| 555 | # Shahrivar. |
| 556 | # |
| 557 | # First Deputy to the President - Hassan Habibi |
| 558 | # |
| 559 | # From personal experience, that agrees with what has been followed |
| 560 | # for at least the last 5 years. Before that, for a few years, the |
| 561 | # date used was the first Thursday night of Farvardin and the last |
| 562 | # Thursday night of Shahrivar, but I can't give exact dates.... |
| 563 | # I have also changed the abbreviations to what is considered correct |
| 564 | # here in Iran, IRST for regular time and IRDT for daylight saving time. |
| 565 | # |
| 566 | # From Roozbeh Pournader (2005-04-05): |
| 567 | # The text of the Iranian law, in effect since 1925, clearly mentions |
| 568 | # that the true solar year is the measure, and there is no arithmetic |
| 569 | # leap year calculation involved. There has never been any serious |
| 570 | # plan to change that law.... |
| 571 | # |
| 572 | # From Paul Eggert (2006-03-22): |
| 573 | # Go with Shanks & Pottenger before Sept. 1991, and with Pournader thereafter. |
| 574 | # I used Ed Reingold's cal-persia in GNU Emacs 21.2 to check Persian dates, |
| 575 | # stopping after 2037 when 32-bit time_t's overflow. |
| 576 | # That cal-persia used Birashk's approximation, which disagrees with the solar |
| 577 | # calendar predictions for the year 2025, so I corrected those dates by hand. |
| 578 | # |
| 579 | # From Oscar van Vlijmen (2005-03-30), writing about future |
| 580 | # discrepancies between cal-persia and the Iranian calendar: |
| 581 | # For 2091 solar-longitude-after yields 2091-03-20 08:40:07.7 UT for |
| 582 | # the vernal equinox and that gets so close to 12:00 some local |
| 583 | # Iranian time that the definition of the correct location needs to be |
| 584 | # known exactly, amongst other factors. 2157 is even closer: |
| 585 | # 2157-03-20 08:37:15.5 UT. But the Gregorian year 2025 should give |
| 586 | # no interpretation problem whatsoever. By the way, another instant |
| 587 | # in the near future where there will be a discrepancy between |
| 588 | # arithmetical and astronomical Iranian calendars will be in 2058: |
| 589 | # vernal equinox on 2058-03-20 09:03:05.9 UT. The Java version of |
| 590 | # Reingold's/Dershowitz' calculator gives correctly the Gregorian date |
| 591 | # 2058-03-21 for 1 Farvardin 1437 (astronomical). |
| 592 | # |
| 593 | # From Steffen Thorsen (2006-03-22): |
| 594 | # Several of my users have reported that Iran will not observe DST anymore: |

| 699 | # From Ephraim Silverberg (2001-01-11): |
| 700 | # |
| 701 | # I coined "IST/IDT" circa 1988. Until then there were three |
| 702 | # different abbreviations in use: |
| 703 | # |
| 704 | # JST Jerusalem Standard Time [Danny Braniss, Hebrew University] |
| 705 | # IZT Israel Zonal (sic) Time [Prof. Haim Papo, Technion] |
| 706 | # EEST Eastern Europe Standard Time [used by almost everyone else] |
| 707 | # |
| 708 | # Since timezones should be called by country and not capital cities, |
| 709 | # I ruled out JST. As Israel is in Asia Minor and not Eastern Europe, |
| 710 | # EEST was equally unacceptable. Since "zonal" was not compatible with |
| 711 | # any other timezone abbreviation, I felt that 'IST' was the way to go |
| 712 | # and, indeed, it has received almost universal acceptance in timezone |
| 713 | # settings in Israeli computers. |
| 714 | # |
| 715 | # In any case, I am happy to share timezone abbreviations with India, |
| 716 | # high on my favorite-country list (and not only because my wife's |
| 717 | # family is from India). |

| 765 | |
| 766 | # According to the Office of the Secretary General of the Ministry of |
| 767 | # Interior, there is NO set rule for Daylight-Savings/Standard time changes. |
| 768 | # One thing is entrenched in law, however: that there must be at least 150 |
| 769 | # days of daylight savings time annually. From 1993-1998, the change to |
| 770 | # daylight savings time was on a Friday morning from midnight IST to |
| 771 | # 1 a.m IDT; up until 1998, the change back to standard time was on a |
| 772 | # Saturday night from midnight daylight savings time to 11 p.m. standard |
| 773 | # time. 1996 is an exception to this rule where the change back to standard |
| 774 | # time took place on Sunday night instead of Saturday night to avoid |
| 775 | # conflicts with the Jewish New Year. In 1999, the change to |
| 776 | # daylight savings time was still on a Friday morning but from |
| 777 | # 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time |
| 778 | # was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for |
| 779 | # 1999 only. In the year 2000, the change to daylight savings time was |
| 780 | # similar to 1999, but although the change back will be on a Friday, it |
| 781 | # will take place from 1 a.m. IDT to midnight IST. Starting in 2001, all |
| 782 | # changes to/from will take place at 1 a.m. old time, but now there is no |
| 783 | # rule as to what day of the week it will take place in as the start date |
| 784 | # (except in 2003) is the night after the Passover Seder (i.e. the eve |
| 785 | # of the 16th of Nisan in the lunar Hebrew calendar) and the end date |
| 786 | # (except in 2002) is three nights before Yom Kippur [Day of Atonement] |

| 976 | # The law is enacted on 1886-07-07. |
| 977 | |
| 978 | # From Hideyuki Suzuki (1998-11-16): |
| 979 | # The ordinance No. 51 (1886) established "standard time" in Japan, |
| 980 | # which stands for the time on E 135 degree. |
| 981 | # In the ordinance No. 167 (1895), "standard time" was renamed to "central |
| 982 | # standard time". And the same ordinance also established "western standard |
| 983 | # time", which stands for the time on E 120 degree.... But "western standard |
| 984 | # time" was abolished in the ordinance No. 529 (1937). In the ordinance No. |
| 985 | # 167, there is no mention regarding for what place western standard time is |
| 986 | # standard.... |
| 987 | # |
| 988 | # I wrote "ordinance" above, but I don't know how to translate. |
| 989 | # In Japanese it's "chokurei", which means ordinance from emperor. |
| 990 | |
| 991 | # Shanks & Pottenger claim JST in use since 1896, and that a few |
| 992 | # places (e.g. Ishigaki) use +0800; go with Suzuki. Guess that all |
| 993 | # ordinances took effect on Jan 1. |

| 1067 | # Guess that Aqtau and Aqtobe diverged in 1995, since that's the first time |

| 1070 | # From Paul Eggert (2006-03-22): |
| 1071 | # German Iofis, ELSI, Almaty (2001-10-09) reports that Kazakhstan uses |

| 1073 | # Go with Shanks & Pottenger, who have them always using RussiaAsia rules. |
| 1074 | # Also go with the following claims of Shanks & Pottenger: |
| 1075 | # |
| 1076 | # - Kazakhstan did not observe DST in 1991. |
| 1077 | # - Qyzylorda switched from +5:00 to +6:00 on 1992-01-19 02:00. |

| 1082 | # </a> |
| 1083 | # The Government of Kazakhstan passed a resolution March 15 abolishing |
| 1084 | # daylight saving time citing lack of economic benefits and health |
| 1085 | # complications coupled with a decrease in productivity. |
| 1086 | # |
| 1087 | # From Branislav Kojic (in Astana) via Gwillim Law (2005-06-28): |
| 1088 | # ... what happened was that the former Kazakhstan Eastern time zone |
| 1089 | # was "blended" with the Central zone. Therefore, Kazakhstan now has |
| 1090 | # two time zones, and difference between them is one hour. The zone |
| 1091 | # closer to UTC is the former Western zone (probably still called the |
| 1092 | # same), encompassing four provinces in the west: Aqtobe, Atyrau, |
| 1093 | # Mangghystau, and West Kazakhstan. The other zone encompasses |
| 1094 | # everything else.... I guess that would make Kazakhstan time zones |

| 1312 | # "Time: Mongolia has two time zones. Three westernmost provinces of |
| 1313 | # Bayan-Ulgii, Uvs, and Hovd are one hour earlier than the capital city, and |
| 1314 | # the rest of the country follows the Ulaanbaatar time, which is UTC/GMT plus |

| 1316 | |
| 1317 | # From Rives McDow (1999-12-13): |
| 1318 | # Mongolia discontinued the use of daylight savings time in 1999; 1998 |
| 1319 | # being the last year it was implemented. The dates of implementation I am |
| 1320 | # unsure of, but most probably it was similar to Russia, except for the time |
| 1321 | # of implementation may have been different.... |
| 1322 | # Some maps in the past have indicated that there was an additional time |

| 1326 | # From Paul Eggert (1999-12-15): |
| 1327 | # Naming and spelling is tricky in Mongolia. |
| 1328 | # We'll use Hovd (also spelled Chovd and Khovd) to represent the west zone; |
| 1329 | # the capital of the Hovd province is sometimes called Hovd, sometimes Dund-Us, |
| 1330 | # and sometimes Jirgalanta (with variant spellings), but the name Hovd |
| 1331 | # is good enough for our purposes. |

| 1476 | # From Amos Shapir (1998-02-15): |
| 1477 | # |
| 1478 | # From 1917 until 1948-05-15, all of Palestine, including the parts now |
| 1479 | # known as the Gaza Strip and the West Bank, was under British rule. |
| 1480 | # Therefore the rules given for Israel for that period, apply there too... |
| 1481 | # |
| 1482 | # The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05 |
| 1483 | # (except a short occupation by Israel from 1956-11 till 1957-03, but no |
| 1484 | # time zone was affected then). It was never formally annexed to Egypt, |
| 1485 | # though. |
| 1486 | # |
| 1487 | # The rest of Palestine was under Jordanian rule at that time, formally |
| 1488 | # annexed in 1950 as the West Bank (and the word "Trans" was dropped from |
| 1489 | # the country's previous name of "the Hashemite Kingdom of the |
| 1490 | # Trans-Jordan"). So the rules for Jordan for that time apply. Major |
| 1491 | # towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and |
| 1492 | # East Jerusalem. |
| 1493 | # |
| 1494 | # Both areas were occupied by Israel in June 1967, but not annexed (except |
| 1495 | # for East Jerusalem). They were on Israel time since then; there might |
| 1496 | # have been a Military Governor's order about time zones, but I'm not aware |
| 1497 | # of any (such orders may have been issued semi-annually whenever summer |
| 1498 | # time was in effect, but maybe the legal aspect of time was just neglected). |
| 1499 | # |
| 1500 | # The Palestinian Authority was established in 1993, and got hold of most |
| 1501 | # towns in the West Bank and Gaza by 1995. I know that in order to |
| 1502 | # demonstrate...independence, they have been switching to |
| 1503 | # summer time and back on a different schedule than Israel's, but I don't |
| 1504 | # know when this was started, or what algorithm is used (most likely the |
| 1505 | # Jordanian one). |
| 1506 | # |
| 1507 | # To summarize, the table should probably look something like that: |

| 1520 | # with Shapir and assume that it observed DST from 1940 through 1947, |
| 1521 | # and that it used Jordanian rules starting in 1996. |
| 1522 | # We don't yet need a separate entry for the West Bank, since |
| 1523 | # the only differences between it and Gaza that we know about |
| 1524 | # occurred before our cutoff date of 1970. |

| 1699 | # [The Tamil Tigers] never accepted the original 1996 time change and simply |
| 1700 | # kept their clocks set five and a half hours ahead of Greenwich Mean |
| 1701 | # Time (GMT), in line with neighbor India. |
| 1702 | # From Paul Eggert (2006-04-18): |
| 1703 | # People who live in regions under Tamil control can use TZ='Asia/Calcutta', |
| 1704 | # as that zone has agreed with the Tamil areas since our cutoff date of 1970. |
| 1705 | |
| 1706 | # From K Sethu (2006-04-25): |
| 1707 | # I think the abbreviation LKT originated from the world of computers at |
| 1708 | # the time of or subsequent to the time zone changes by SL Government |
| 1709 | # twice in 1996 and probably SL Government or its standardization |
| 1710 | # agencies never declared an abbreviation as a national standard. |
| 1711 | # |
| 1712 | # I recollect before the recent change the government annoucemments |
| 1713 | # mentioning it as simply changing Sri Lanka Standard Time or Sri Lanka |
| 1714 | # Time and no mention was made about the abbreviation. |
| 1715 | # |
| 1716 | # If we look at Sri Lanka Department of Government's "Official News |
| 1717 | # Website of Sri Lanka" ... http://www.news.lk/ we can see that they |
| 1718 | # use SLT as abbreviation in time stamp at the beginning of each news |
| 1719 | # item.... |
| 1720 | # |
| 1721 | # Within Sri Lanka I think LKT is well known among computer users and |
| 1722 | # adminsitrators. In my opinion SLT may not be a good choice because the |
| 1723 | # nation's largest telcom / internet operator Sri Lanka Telcom is well |
| 1724 | # known by that abbreviation - simply as SLT (there IP domains are |
| 1725 | # slt.lk and sltnet.lk). |
| 1726 | # |
| 1727 | # But if indeed our government has adopted SLT as standard abbreviation |
| 1728 | # (that we have not known so far) then it is better that it be used for |
| 1729 | # all computers. |
| 1730 | |
| 1731 | # From Paul Eggert (2006-04-25): |
| 1732 | # One possibility is that we wait for a bit for the dust to settle down |
| 1733 | # and then see what people actually say in practice. |
