2864e767 UD |
10 | # Thomas G. Shanks, The International Atlas (5th edition), |
11 | # San Diego: ACS Publications, Inc. (1999). | |
28f540f4 | 12 | # |
1f5649f8 | 13 | # Gwillim Law writes that a good source |
8a523922 UD |
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. | |

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. | |

546 | # From Ephraim Silverberg (2001-01-11): |
547 | # | |
548 | # I coined "IST/IDT" circa 1988. Until then there were three | |
549 | # different abbreviations in use: | |
550 | # | |
551 | # JST Jerusalem Standard Time [Danny Braniss, Hebrew University] | |
552 | # IZT Israel Zonal (sic) Time [Prof. Haim Papo, Technion] | |
553 | # EEST Eastern Europe Standard Time [used by almost everyone else] | |
554 | # | |
555 | # Since timezones should be called by country and not capital cities, | |
556 | # I ruled out JST. As Israel is in Asia Minor and not Eastern Europe, | |
557 | # EEST was equally unacceptable. Since "zonal" was not compatible with | |
558 | # any other timezone abbreviation, I felt that 'IST' was the way to go | |
559 | # and, indeed, it has received almost universal acceptance in timezone | |
560 | # settings in Israeli computers. | |
561 | # | |
562 | # In any case, I am happy to share timezone abbreviations with India, | |
563 | # high on my favorite-country list (and not only because my wife's | |
564 | # family is from India). | |

74015205 | 609 | # From Ephraim Silverberg <ephraim@cs.huji.ac.il> |
89533d41 | 610 | # (1997-03-04, 1998-03-16, 1998-12-28, 2000-01-17 and 2000-07-25): |

612 | # According to the Office of the Secretary General of the Ministry of |
613 | # Interior, there is NO set rule for Daylight-Savings/Standard time changes. | |
b21c5832 AS |
614 | # One thing is entrenched in law, however: that there must be at least 150 |
615 | # days of daylight savings time annually. From 1993-1998, the change to | |
616 | # daylight savings time was on a Friday morning from midnight IST to | |
617 | # 1 a.m IDT; up until 1998, the change back to standard time was on a | |
618 | # Saturday night from midnight daylight savings time to 11 p.m. standard | |
619 | # time. 1996 is an exception to this rule where the change back to standard | |
620 | # time took place on Sunday night instead of Saturday night to avoid | |
89533d41 UD |
621 | # conflicts with the Jewish New Year. In 1999, the change to |
622 | # daylight savings time was still on a Friday morning but from | |
b21c5832 | 623 | # 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time |
89533d41 UD |
624 | # was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for |
625 | # 1999 only. In the year 2000, the change to daylight savings time was | |
626 | # similar to 1999, but although the change back will be on a Friday, it | |
627 | # will take place from 1 a.m. IDT to midnight IST. Starting in 2001, all | |
628 | # changes to/from will take place at 1 a.m. old time, but now there is no | |
629 | # rule as to what day of the week it will take place in as the start date | |
630 | # (except in 2003) is the night after the Passover Seder (i.e. the eve | |
631 | # of the 16th of Nisan in the lunar Hebrew calendar) and the end date | |
632 | # (except in 2002) is three nights before Yom Kippur [Day of Atonement] | |
633 | # (the eve of the 7th of Tishrei in the lunar Hebrew calendar). | |

726 | # Today's _Asahi Evening News_ (page 4) reports that Japan had | |
727 | # daylight saving between 1948 and 1951, but ``the system was discontinued | |
728 | # because the public believed it would lead to longer working hours.'' | |

738 | # From Hideyuki Suzuki (1998-11-09): |
739 | # 'Tokyo' usually stands for the former location of Tokyo Astronomical | |

741 | # This data is from 'Rika Nenpyou (Chronological Scientific Tables) 1996' | |

743 | # JST (Japan Standard Time) has been used since 1888-01-01 00:00 (JST). | |
744 | # The law is enacted on 1886-07-07. | |
745 | ||
746 | # From Hideyuki Suzuki (1998-11-16): | |
747 | # The ordinance No. 51 (1886) established "standard time" in Japan, | |
748 | # which stands for the time on E 135 degree. | |
749 | # In the ordinance No. 167 (1895), "standard time" was renamed to "central | |
750 | # standard time". And the same ordinance also established "western standard | |
751 | # time", which stands for the time on E 120 degree.... But "western standard | |
752 | # time" was abolished in the ordinance No. 529 (1937). In the ordinance No. | |
753 | # 167, there is no mention regarding for what place western standard time is | |
754 | # standard.... | |
755 | # | |
756 | # I wrote "ordinance" above, but I don't know how to translate. | |
757 | # In Japanese it's "chokurei", which means ordinance from emperor. | |
758 | ||
759 | # Shanks claims JST in use since 1896, and that a few places (e.g. Ishigaki) | |
760 | # use +0800; go with Suzuki. Guess that all ordinances took effect on Jan 1. | |

1055 | # From Amos Shapir <amos@nsof.co.il> (1998-02-15): | |
1056 | # | |
1057 | # From 1917 until 1948-05-15, all of Palestine, including the parts now | |
1058 | # known as the Gaza Strip and the West Bank, was under British rule. | |
1059 | # Therefore the rules given for Israel for that period, apply there too... | |
1060 | # | |
1061 | # The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05 | |
1062 | # (except a short occupation by Israel from 1956-11 till 1957-03, but no | |
1063 | # time zone was affected then). It was never formally annexed to Egypt, | |
1064 | # though. | |
1065 | # | |
1066 | # The rest of Palestine was under Jordanian rule at that time, formally | |
1067 | # annexed in 1950 as the West Bank (and the word "Trans" was dropped from | |
1068 | # the country's previous name of "the Hashemite Kingdom of the | |
1069 | # Trans-Jordan"). So the rules for Jordan for that time apply. Major | |
1070 | # towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and | |
1071 | # East Jerusalem. | |
1072 | # | |
1073 | # Both areas were occupied by Israel in June 1967, but not annexed (except | |
1074 | # for East Jerusalem). They were on Israel time since then; there might | |
1075 | # have been a Military Governor's order about time zones, but I'm not aware | |
1076 | # of any (such orders may have been issued semi-annually whenever summer | |
1077 | # time was in effect, but maybe the legal aspect of time was just neglected). | |
1078 | # | |
1079 | # The Palestinian Authority was established in 1993, and got hold of most | |
1080 | # towns in the West Bank and Gaza by 1995. I know that in order to | |
1081 | # demonstrate...independence, they have been switching to | |
1082 | # summer time and back on a different schedule than Israel's, but I don't | |
1083 | # know when this was started, or what algorithm is used (most likely the | |
1084 | # Jordanian one). | |
1085 | # | |
1086 | # To summarize, the table should probably look something like that: | |
1087 | # | |
1088 | # Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996- | |

1096 | ||
1097 | # From Paul Eggert (1998-02-25): | |
1098 | # Shanks writes that Gaza did not observe DST until 1957, but we'll go | |
1099 | # with Shapir and assume that it observed DST from 1940 through 1947, | |
1100 | # and that it used Jordanian rules starting in 1996. | |
1101 | # We don't yet need a separate entry for the West Bank, since | |
1102 | # the only differences between it and Gaza that we know about | |
1103 | # occurred before our cutoff date of 1970. | |
1104 | # However, as we get more information, we may need to add entries | |
1105 | # for parts of the West Bank as they transitioned from Israel's rules | |
1106 | # to Palestine's rules. If you have more info about this, please | |
