  45. # From Alex Livingston (1996-11-01):
  46. # I have heard or read more than once that some resort islands off the coast
  47. # of Queensland chose to keep observing daylight-saving time even after
  48. # Queensland ceased to.
  49. #
  50. # From Paul Eggert (1996-11-22):
  51. # IATA SSIM (1993-02/1994-09) say that the Holiday Islands (Hayman, Lindeman,
  52. # Hamilton) observed DST for two years after the rest of Queensland stopped.
  53. # Hamilton is the largest, but there is also a Hamilton in Victoria,
  54. # so use Lindeman.

  772. # or `Eastern Summer Time'. (Note, though, that as I say in the
  773. # current australasia file, there is really no such thing.) Announcers
  774. # on its overseas service, Radio Australia, use the same phrases
  775. # prefixed by the word `Australian' when referring to local times;
  776. # time announcements on that service, naturally enough, are made in UTC.
  777. # From Arthur David Olson (1992-03-08):
  778. # Given the above, what's chosen for year-round use is:
  779. # CST for any place operating at a GMTOFF of 9:30
  780. # WST for any place operating at a GMTOFF of 8:00
  781. # EST for any place operating at a GMTOFF of 10:00
  782. # From Chuck Soper (2006-06-01):
  783. # I recently found this Australian government web page on time zones:
  784. # <http://www.australia.gov.au/about-australia-13time>
  785. # And this government web page lists time zone names and abbreviations:
  786. # <http://www.bom.gov.au/climate/averages/tables/daysavtm.shtml>
  787. # From Paul Eggert (2001-04-05), summarizing a long discussion about "EST"
  788. # versus "AEST" etc.:
  789. #
  790. # I see the following points of dispute:
  791. #
  792. # * How important are unique time zone abbreviations?
  793. #
  794. # Here I tend to agree with the point (most recently made by Chris
  795. # Newman) that unique abbreviations should not be essential for proper
  796. # operation of software. We have other instances of ambiguity
  797. # (e.g. "IST" denoting both "Israel Standard Time" and "Indian
  798. # Standard Time"), and they are not likely to go away any time soon.
  799. # In the old days, some software mistakenly relied on unique
  800. # abbreviations, but this is becoming less true with time, and I don't
  801. # think it's that important to cater to such software these days.
  802. #
  803. # On the other hand, there is another motivation for unambiguous
  804. # abbreviations: it cuts down on human confusion. This is
  805. # particularly true for Australia, where "EST" can mean one thing for
  806. # time T and a different thing for time T plus 1 second.
  807. #
  808. # * Does the relevant legislation indicate which abbreviations should be used?
  809. #
  810. # Here I tend to think that things are a mess, just as they are in
  811. # many other countries. We Americans are currently disagreeing about
  812. # which abbreviation to use for the newly legislated Chamorro Standard
  813. # Time, for example.
  814. #
  815. # Personally, I would prefer to use common practice; I would like to
  816. # refer to legislation only for examples of common practice, or as a
  817. # tiebreaker.
  818. #
  819. # * Do Australians more often use "Eastern Daylight Time" or "Eastern
  820. # Summer Time"? Do they typically prefix the time zone names with
  821. # the word "Australian"?
  822. #
  823. # My own impression is that both "Daylight Time" and "Summer Time" are
  824. # common and are widely understood, but that "Summer Time" is more
  825. # popular; and that the leading "A" is also common but is omitted more
  826. # often than not. I just used AltaVista advanced search and got the
  827. # following count of page hits:
  828. #
  829. # 1,103 "Eastern Summer Time" AND domain:au
  830. # 971 "Australian Eastern Summer Time" AND domain:au
  831. # 613 "Eastern Daylight Time" AND domain:au
  832. # 127 "Australian Eastern Daylight Time" AND domain:au
  833. #
  834. # Here "Summer" seems quite a bit more popular than "Daylight",
  835. # particularly when we know the time zone is Australian and not US,
  836. # say. The "Australian" prefix seems to be popular for Eastern Summer
  837. # Time, but unpopular for Eastern Daylight Time.
  838. #
  839. # For abbreviations, tools like AltaVista are less useful because of
  840. # ambiguity. Many hits are not really time zones, unfortunately, and
  841. # many hits denote US time zones and not Australian ones. But here
  842. # are the hit counts anyway:
  843. #
  844. # 161,304 "EST" and domain:au
  845. # 25,156 "EDT" and domain:au
  846. # 18,263 "AEST" and domain:au
  847. # 10,416 "AEDT" and domain:au
  848. #
  849. # 14,538 "CST" and domain:au
  850. # 5,728 "CDT" and domain:au
  851. # 176 "ACST" and domain:au
  852. # 29 "ACDT" and domain:au
  853. #
  854. # 7,539 "WST" and domain:au
  855. # 68 "AWST" and domain:au
  856. #
  857. # This data suggest that Australians tend to omit the "A" prefix in
  858. # practice. The situation for "ST" versus "DT" is less clear, given
  859. # the ambiguities involved.
  860. #
  861. # * How do Australians feel about the abbreviations in the tz database?
  862. #
  863. # If you just count Australians on this list, I count 2 in favor and 3
  864. # against. One of the "against" votes (David Keegel) counseled delay,
  865. # saying that both AEST/AEDT and EST/EST are widely used and
  866. # understood in Australia.

  1096. # in Melbourne, Australia.

  1104. #
  1105. # However, that is only because of some special mirror contraption that had

  1388. # </a>:
  1389. # Until 1941 Tonga maintained a standard time 50 minutes ahead of NZST
  1390. # 12 hours and 20 minutes ahead of GMT. When New Zealand adjusted its
  1391. # standard time in 1940s, Tonga had the choice of subtracting from its
  1392. # local time to come on the same standard time as New Zealand or of
  1393. # advancing its time to maintain the differential of 13 degrees
  1394. # (approximately 50 minutes ahead of New Zealand time).

  1396. # Because His Majesty King Taufa'ahau Tupou IV, then Crown Prince
  1397. # Tungi, preferred to ensure Tonga's title as the land where time
  1398. # begins, the Legislative Assembly approved the latter change.
  1399. #
  1400. # But some of the older, more conservative members from the outer
  1401. # islands objected. "If at midnight on Dec. 31, we move ahead 40
  1402. # minutes, as your Royal Highness wishes, what becomes of the 40
  1403. # minutes we have lost?"
  1404. #
  1405. # The Crown Prince, presented an unanswerable argument: "Remember that
  1406. # on the World Day of Prayer, you would be the first people on Earth
  1407. # to say your prayers in the morning."

  1459. # US Ambassador At Large (oral history interview, 1971-02-02):
  1460. #
  1461. # Saturday, the 14th [of October, 1950] -- ... The time was all the
  1462. # more confusing at that point, because we had crossed the
  1463. # International Date Line, thus getting two Sundays. Furthermore, we
  1464. # discovered that Wake Island had two hours of daylight saving time
  1465. # making calculation of time in Washington difficult if not almost
  1466. # impossible.

  1472. # The International Date Line
  1473. # From Gwillim Law (2000-01-03):
  1474. #
  1475. # The International Date Line is not defined by any international standard,
  1476. # convention, or treaty. Mapmakers are free to draw it as they please.
  1477. # Reputable mapmakers will simply ensure that every point of land appears on
  1478. # the correct side of the IDL, according to the date legally observed there.
  1479. #
  1480. # When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and
  1481. # Line Islands to the west side of the IDL (or, if you prefer, moving the IDL
  1482. # to the east side of the Phoenix and Line Islands), I suppose that most
  1483. # mapmakers redrew the IDL following the boundary of Kiribati. Even that line
  1484. # has a rather arbitrary nature. The straight-line boundaries between Pacific
  1485. # island nations that are shown on many maps are based on an international
  1486. # convention, but are not legally binding national borders.... The date is
  1487. # governed by the IDL; therefore, even on the high seas, there may be some
  1488. # places as late as fourteen hours later than UTC. And, since the IDL is not
  1489. # an international standard, there are some places on the high seas where the
  1490. # correct date is ambiguous.
  1491. # From Wikipedia <http://en.wikipedia.org/wiki/Time_zone> (2005-08-31):
  1492. # Before 1920, all ships kept local apparent time on the high seas by setting
  1493. # their clocks at night or at the morning sight so that, given the ship's
  1494. # speed and direction, it would be 12 o'clock when the Sun crossed the ship's
  1495. # meridian (12 o'clock = local apparent noon). During 1917, at the
  1496. # Anglo-French Conference on Time-keeping at Sea, it was recommended that all
  1497. # ships, both military and civilian, should adopt hourly standard time zones
  1498. # on the high seas. Whenever a ship was within the territorial waters of any
  1499. # nation it would use that nation's standard time. The captain was permitted
  1500. # to change his ship's clocks at a time of his choice following his ship's
  1501. # entry into another zone time--he often chose midnight. These zones were
  1502. # adopted by all major fleets between 1920 and 1925 but not by many
  1503. # independent merchant ships until World War II.

  1510. # international waters; it ignores the international date line.
