55 | # I have heard or read more than once that some resort islands off the coast |
56 | # of Queensland chose to keep observing daylight-saving time even after | |
57 | # Queensland ceased to. | |
58 | # | |
59 | # From Paul Eggert (1996-11-22): | |
60 | # IATA SSIM (1993-02/1994-09) say that the Holiday Islands (Hayman, Lindeman, | |
61 | # Hamilton) observed DST for two years after the rest of Queensland stopped. | |
62 | # Hamilton is the largest, but there is also a Hamilton in Victoria, | |
63 | # so use Lindeman. | |

28f540f4 RM |
601 | # We in Australia have _never_ referred to DST as `daylight' time. |
602 | # It is called `summer' time. Now by a happy coincidence, `summer' | |
603 | # and `standard' happen to start with the same letter; hence, the | |
604 | # abbreviation does _not_ change... | |
605 | # The legislation does not actually define abbreviations, at least | |
606 | # in this State, but the abbreviation is just commonly taken to be the | |
607 | # initials of the phrase, and the legislation here uniformly uses | |
608 | # the phrase `summer time' and does not use the phrase `daylight | |
609 | # time'. | |
610 | # Announcers on the Commonwealth radio network, the ABC (for Australian | |
611 | # Broadcasting Commission), use the phrases `Eastern Standard Time' | |
612 | # or `Eastern Summer Time'. (Note, though, that as I say in the | |
613 | # current australasia file, there is really no such thing.) Announcers | |
614 | # on its overseas service, Radio Australia, use the same phrases | |
615 | # prefixed by the word `Australian' when referring to local times; | |
616 | # time announcements on that service, naturally enough, are made in UTC. | |

1f5649f8 UD |
630 | # From Paul Eggert (2001-04-05), summarizing a long discussion about "EST" |
631 | # versus "AEST" etc.: | |
632 | # | |
633 | # I see the following points of dispute: | |
634 | # | |
635 | # * How important are unique time zone abbreviations? | |
636 | # | |
637 | # Here I tend to agree with the point (most recently made by Chris | |
638 | # Newman) that unique abbreviations should not be essential for proper | |
639 | # operation of software. We have other instances of ambiguity | |
640 | # (e.g. "IST" denoting both "Israel Standard Time" and "Indian | |
641 | # Standard Time"), and they are not likely to go away any time soon. | |
642 | # In the old days, some software mistakenly relied on unique | |
643 | # abbreviations, but this is becoming less true with time, and I don't | |
644 | # think it's that important to cater to such software these days. | |
645 | # | |
646 | # On the other hand, there is another motivation for unambiguous | |
647 | # abbreviations: it cuts down on human confusion. This is | |
648 | # particularly true for Australia, where "EST" can mean one thing for | |
649 | # time T and a different thing for time T plus 1 second. | |
650 | # | |
651 | # * Does the relevant legislation indicate which abbreviations should be used? | |
652 | # | |
653 | # Here I tend to think that things are a mess, just as they are in | |
654 | # many other countries. We Americans are currently disagreeing about | |
655 | # which abbreviation to use for the newly legislated Chamorro Standard | |
656 | # Time, for example. | |
657 | # | |
658 | # Personally, I would prefer to use common practice; I would like to | |
659 | # refer to legislation only for examples of common practice, or as a | |
660 | # tiebreaker. | |
661 | # | |
662 | # * Do Australians more often use "Eastern Daylight Time" or "Eastern | |
663 | # Summer Time"? Do they typically prefix the time zone names with | |
664 | # the word "Australian"? | |
665 | # | |
666 | # My own impression is that both "Daylight Time" and "Summer Time" are | |
667 | # common and are widely understood, but that "Summer Time" is more | |
668 | # popular; and that the leading "A" is also common but is omitted more | |
669 | # often than not. I just used AltaVista advanced search and got the | |
670 | # following count of page hits: | |
671 | # | |
672 | # 1,103 "Eastern Summer Time" AND domain:au | |
673 | # 971 "Australian Eastern Summer Time" AND domain:au | |
674 | # 613 "Eastern Daylight Time" AND domain:au | |
675 | # 127 "Australian Eastern Daylight Time" AND domain:au | |
676 | # | |
677 | # Here "Summer" seems quite a bit more popular than "Daylight", | |
678 | # particularly when we know the time zone is Australian and not US, | |
679 | # say. The "Australian" prefix seems to be popular for Eastern Summer | |
680 | # Time, but unpopular for Eastern Daylight Time. | |
681 | # | |
682 | # For abbreviations, tools like AltaVista are less useful because of | |
683 | # ambiguity. Many hits are not really time zones, unfortunately, and | |
684 | # many hits denote US time zones and not Australian ones. But here | |
685 | # are the hit counts anyway: | |
686 | # | |
687 | # 161,304 "EST" and domain:au | |
688 | # 25,156 "EDT" and domain:au | |
689 | # 18,263 "AEST" and domain:au | |
690 | # 10,416 "AEDT" and domain:au | |
691 | # | |
692 | # 14,538 "CST" and domain:au | |
693 | # 5,728 "CDT" and domain:au | |
694 | # 176 "ACST" and domain:au | |
695 | # 29 "ACDT" and domain:au | |
696 | # | |
697 | # 7,539 "WST" and domain:au | |
698 | # 68 "AWST" and domain:au | |
699 | # | |
700 | # This data suggest that Australians tend to omit the "A" prefix in | |
701 | # practice. The situation for "ST" versus "DT" is less clear, given | |
702 | # the ambiguities involved. | |
703 | # | |
704 | # * How do Australians feel about the abbreviations in the tz database? | |
705 | # | |
706 | # If you just count Australians on this list, I count 2 in favor and 3 | |
707 | # against. One of the "against" votes (David Keegel) counseled delay, | |
708 | # saying that both AEST/AEDT and EST/EST are widely used and | |
709 | # understood in Australia. | |

863 | # ... it was just on four years ago that I drove along the Eyre Highway, | |

865 | # coast of the continent. | |
866 | # | |
867 | # I paid particular attention to the time kept there. There can be no | |
868 | # dispute that UTC+08:45 was considered "the time" from the border | |
869 | # village just inside the border with South Australia to as far west | |
870 | # as just east of Caiguna. There can also be no dispute that Eucla is | |

976 | # From Scott Harrington (2001-08-29): |
977 | # On KQED's "City Arts and Lectures" program last night I heard an | |
978 | # interesting story about daylight savings time. Dr. John Heilbron was | |
979 | # discussing his book "The Sun in the Church: Cathedrals as Solar | |
980 | # Observatories"[1], and in particular the Shrine of Remembrance[2] located | |
981 | # in Melbourne, Australia. | |
982 | # | |
983 | # Apparently the shrine's main purpose is a beam of sunlight which | |
984 | # illuminates a special spot on the floor at the 11th hour of the 11th day | |
985 | # of the 11th month (Remembrance Day) every year in memory of Australia's | |
986 | # fallen WWI soldiers. And if you go there on Nov. 11, at 11am local time, | |
987 | # you will indeed see the sunbeam illuminate the special spot at the | |
988 | # expected time. | |
989 | # | |
990 | # However, that is only because of some special mirror contraption that had | |
991 | # to be employed, since due to daylight savings time, the true solar time of | |
992 | # the remembrance moment occurs one hour later (or earlier?). Perhaps | |
993 | # someone with more information on this jury-rig can tell us more. | |

1337 | ||
1338 | # Until 1941 Tonga maintained a standard time 50 minutes ahead of NZST | |
1339 | # 12 hours and 20 minutes ahead of GMT. When New Zealand adjusted its | |
1340 | # standard time in 1940s, Tonga had the choice of subtracting from its | |
1341 | # local time to come on the same standard time as New Zealand or of | |
1342 | # advancing its time to maintain the differential of 13 degrees | |
1343 | # (approximately 50 minutes ahead of New Zealand time). | |
1344 | # | |
1345 | # Because His Majesty King Taufa'ahau Tupou IV, then Crown Prince | |
1346 | # Tungi, preferred to ensure Tonga's title as the land where time | |
1347 | # begins, the Legislative Assembly approved the latter change. | |
1348 | # | |
1349 | # But some of the older, more conservative members from the outer | |
1350 | # islands objected. "If at midnight on Dec. 31, we move ahead 40 | |
a7123f0e | 1351 | # minutes, as your Royal Highness wishes, what becomes of the 40 |
38c097ca UD |
1352 | # minutes we have lost?" |

0af4c646 UD |
1440 | # The International Date Line is not defined by any international standard, |
1441 | # convention, or treaty. Mapmakers are free to draw it as they please. | |
1442 | # Reputable mapmakers will simply ensure that every point of land appears on | |
1443 | # the correct side of the IDL, according to the date legally observed there. | |
1444 | # | |
1445 | # When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and | |
1446 | # Line Islands to the west side of the IDL (or, if you prefer, moving the IDL | |
1447 | # to the east side of the Phoenix and Line Islands), I suppose that most | |
1448 | # mapmakers redrew the IDL following the boundary of Kiribati. Even that line | |
1449 | # has a rather arbitrary nature. The straight-line boundaries between Pacific | |
1450 | # island nations that are shown on many maps are based on an international | |
53751fd5 | 1451 | # convention, but are not legally binding national borders.... The date is |
0af4c646 UD |
1452 | # governed by the IDL; therefore, even on the high seas, there may be some |
1453 | # places as late as fourteen hours later than UTC. And, since the IDL is not | |
1454 | # an international standard, there are some places on the high seas where the | |
1455 | # correct date is ambiguous. | |

1457 | # From Wikipedia <http://en.wikipedia.org/wiki/Time_zone> (2005-08-31): |
1458 | # Before 1920, all ships kept local apparent time on the high seas by setting | |
1459 | # their clocks at night or at the morning sight so that, given the ship's | |
1460 | # speed and direction, it would be 12 o'clock when the Sun crossed the ship's | |
1461 | # meridian (12 o'clock = local apparent noon). During 1917, at the | |
1462 | # Anglo-French Conference on Time-keeping at Sea, it was recommended that all | |
1463 | # ships, both military and civilian, should adopt hourly standard time zones | |
1464 | # on the high seas. Whenever a ship was within the territorial waters of any | |
1465 | # nation it would use that nation's standard time. The captain was permitted | |
1466 | # to change his ship's clocks at a time of his choice following his ship's | |
1467 | # entry into another zone time--he often chose midnight. These zones were | |
1468 | # adopted by all major fleets between 1920 and 1925 but not by many | |
