7 | # From Paul Eggert <eggert@twinsun.com> (1999-03-22): | |
8 | # | |
9 | # A good source for time zone historical data outside the U.S. is | |
10 | # Thomas G. Shanks, The International Atlas (5th edition), | |
11 | # San Diego: ACS Publications, Inc. (1999). | |
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 is the source for entries through 1990, | |
20 | # and IATA SSIM is the source for entries after 1990. | |
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). | |

83 | # Armenia | |
84 | # From Paul Eggert (1999-10-29): | |
85 | # Shanks has Yerevan switching to 3:00 (with Russian DST) in spring 1991, | |
86 | # then to 4:00 with no DST in fall 1995, then readopting Russian DST in 1997. | |
87 | # Go with Shanks, even when he disagrees with others. Edgar Der-Danieliantz | |
88 | # <edd@AIC.NET> reported (1996-05-04) that Yerevan probably wouldn't use DST | |
89 | # in 1996, though it did use DST in 1995. IATA SSIM (1991/1998) reports that | |
90 | # Armenia switched from 3:00 to 4:00 in 1998 and observed DST after 1991, | |
91 | # but started switching at 3:00s in 1998. | |

172 | # No they don't. See TIME mag, 1986-02-17 p.52. Even though | |
173 | # China is across 4 physical time zones, before Feb 1, 1986 only the | |

175 | # has two of 'em -- Peking's and Urumqi (named after the capital of | |

327 | # Georgia | |
328 | # From Paul Eggert <eggert@twinsun.com> (1994-11-19): | |
329 | # Today's _Economist_ (p 60) reports that Georgia moved its clocks forward | |
330 | # an hour recently, due to a law proposed by Zurab Murvanidze, | |
331 | # an MP who went on a hunger strike for 11 days to force discussion about it! | |
332 | # We have no details, but we'll guess they didn't move the clocks back in fall. | |
333 | # | |
334 | # From Mathew Englander <mathew@io.org>, quoting AP (1996-10-23 13:05-04): | |
335 | # Instead of putting back clocks at the end of October, Georgia | |
336 | # will stay on daylight savings time this winter to save energy, | |
337 | # President Eduard Shevardnadze decreed Wednesday. | |
338 | # | |
339 | # From the BBC via Joseph S. Myers (2004-06-27): | |
340 | # | |
341 | # Georgia moved closer to Western Europe on Sunday... The former Soviet | |
342 | # republic has changed its time zone back to that of Moscow. As a result it | |

542 | # From Jonathan Lennox <lennox@cs.columbia.edu> (2000-06-12): | |
543 | # An article in this week's Economist ("Inside the Saddam-free zone", p. 50 in | |
544 | # the U.S. edition) on the Iraqi Kurds contains a paragraph: | |
545 | # "The three northern provinces ... switched their clocks this spring and | |
546 | # are an hour ahead of Baghdad." | |
547 | # | |
548 | # But Rives McDow (2000-06-18) quotes a contact in Iraqi-Kurdistan as follows: | |
549 | # In the past, some Kurdish nationalists, as a protest to the Iraqi | |
550 | # Government, did not adhere to daylight saving time. They referred | |
551 | # to daylight saving as Saddam time. But, as of today, the time zone | |
552 | # in Iraqi-Kurdistan is on standard time with Baghdad, Iraq. | |
553 | # | |

578 | # From Ephraim Silverberg (2001-01-11): | |
579 | # | |
580 | # I coined "IST/IDT" circa 1988. Until then there were three | |
581 | # different abbreviations in use: | |
582 | # | |
583 | # JST Jerusalem Standard Time [Danny Braniss, Hebrew University] | |
584 | # IZT Israel Zonal (sic) Time [Prof. Haim Papo, Technion] | |
585 | # EEST Eastern Europe Standard Time [used by almost everyone else] | |
586 | # | |
587 | # Since timezones should be called by country and not capital cities, | |
588 | # I ruled out JST. As Israel is in Asia Minor and not Eastern Europe, | |
589 | # EEST was equally unacceptable. Since "zonal" was not compatible with | |
590 | # any other timezone abbreviation, I felt that 'IST' was the way to go | |
591 | # and, indeed, it has received almost universal acceptance in timezone | |
592 | # settings in Israeli computers. | |
593 | # | |
594 | # In any case, I am happy to share timezone abbreviations with India, | |
595 | # high on my favorite-country list (and not only because my wife's | |
596 | # family is from India). | |

644 | # According to the Office of the Secretary General of the Ministry of | |
645 | # Interior, there is NO set rule for Daylight-Savings/Standard time changes. | |
646 | # One thing is entrenched in law, however: that there must be at least 150 | |
647 | # days of daylight savings time annually. From 1993-1998, the change to | |
648 | # daylight savings time was on a Friday morning from midnight IST to | |
649 | # 1 a.m IDT; up until 1998, the change back to standard time was on a | |
650 | # Saturday night from midnight daylight savings time to 11 p.m. standard | |
651 | # time. 1996 is an exception to this rule where the change back to standard | |
652 | # time took place on Sunday night instead of Saturday night to avoid | |
653 | # conflicts with the Jewish New Year. In 1999, the change to | |
654 | # daylight savings time was still on a Friday morning but from | |
655 | # 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time | |
656 | # was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for | |

750 | # From Ephraim Silverberg (2003-03-23): | |
751 | # | |
752 | # Minister of Interior Poraz has announced that he will respect the law | |
753 | # passed in July 2000 (proposed at the time jointly by himself and | |
754 | # then-MK David Azulai [Shas]) fixing the dates for 2000-2004. Hence, | |
755 | # the dates for 2003 and 2004 remain unchanged.... | |
756 | # | |
757 | # As far as 2005 and beyond, no dates have been set. However, the | |
758 | # minister has mentioned that he wishes to propose to move Israel's | |
759 | # timezone in 2005 from GMT+2 to GMT+3 and upon that have DST during | |
760 | # the summer months (i.e. GMT+4). However, no legislation in this | |
761 | # direction is expected until the latter part of 2004 which is a long | |
762 | # time off in terms of Israeli politics. | |
763 | ||
764 | # (2004-09-20): | |
765 | # The latest rumour, however, is that in 2005, when the clock changes to | |
766 | # Daylight Saving Time (date as yet unknown), the move will be a two-hour leap | |
767 | # forward (from UTC+0200 to UTC+0400) and then, in the fall, the clock will | |
768 | # move back only an hour to UTC+0300 thus effectively moving Israel's timezone | |
769 | # from UTC+0200 to UTC+0300. However, no actual draft has been put before the | |
770 | # Knesset (Israel's Parliament) though the intention is to do so this | |
771 | # month [2004-09]. | |
772 | ||
773 | # (2004-09-26): | |
774 | # Even though the draft law for the above did pass the Ministerial Committee | |
775 | # for Legislative Matters three months ago, it was voted down in today's | |
776 | # Cabinet meeting. The current suggestion is to keep the current timezone at | |
777 | # UTC+0200 but have an extended period of Daylight Saving Time (UTC+0300) from | |
778 | # the beginning of Passover holiday in the spring to after the Tabernacle | |
779 | # holiday in the fall (i.e. the dates of which are governed by the Hebrew | |
780 | # calendar but this means at least 184 days of DST). However, this is only a | |
781 | # suggestion that was raised in today's cabinet meeting and has not yet been | |
782 | # drafted. | |

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

1219 | # From Amos Shapir <amos@nsof.co.il> (1998-02-15): | |
1220 | # | |
1221 | # From 1917 until 1948-05-15, all of Palestine, including the parts now | |
1222 | # known as the Gaza Strip and the West Bank, was under British rule. | |
1223 | # Therefore the rules given for Israel for that period, apply there too... | |
1224 | # | |
1225 | # The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05 | |
1226 | # (except a short occupation by Israel from 1956-11 till 1957-03, but no | |
1227 | # time zone was affected then). It was never formally annexed to Egypt, | |
1228 | # though. | |
1229 | # | |
1230 | # The rest of Palestine was under Jordanian rule at that time, formally | |
1231 | # annexed in 1950 as the West Bank (and the word "Trans" was dropped from | |
1232 | # the country's previous name of "the Hashemite Kingdom of the | |
1233 | # Trans-Jordan"). So the rules for Jordan for that time apply. Major | |
1234 | # towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and | |
1235 | # East Jerusalem. | |
1236 | # | |
1237 | # Both areas were occupied by Israel in June 1967, but not annexed (except | |
1238 | # for East Jerusalem). They were on Israel time since then; there might | |
1239 | # have been a Military Governor's order about time zones, but I'm not aware | |
1240 | # of any (such orders may have been issued semi-annually whenever summer | |
1241 | # time was in effect, but maybe the legal aspect of time was just neglected). | |
1242 | # | |
1243 | # The Palestinian Authority was established in 1993, and got hold of most | |
1244 | # towns in the West Bank and Gaza by 1995. I know that in order to | |
1245 | # demonstrate...independence, they have been switching to | |
1246 | # summer time and back on a different schedule than Israel's, but I don't | |
1247 | # know when this was started, or what algorithm is used (most likely the | |
1248 | # Jordanian one). | |
1249 | # | |
1250 | # To summarize, the table should probably look something like that: | |
1251 | # | |

1259 | # have one). | |
1260 | ||
1261 | # From Paul Eggert (1998-02-25): | |
1262 | # Shanks writes that Gaza did not observe DST until 1957, but we'll go | |
1263 | # with Shapir and assume that it observed DST from 1940 through 1947, | |
1264 | # and that it used Jordanian rules starting in 1996. | |
1265 | # We don't yet need a separate entry for the West Bank, since | |
1266 | # the only differences between it and Gaza that we know about | |
1267 | # occurred before our cutoff date of 1970. | |
1268 | # However, as we get more information, we may need to add entries | |
1269 | # for parts of the West Bank as they transitioned from Israel's rules | |
1270 | # to Palestine's rules. If you have more info about this, please | |
