duke@0 847
duke@0 848 # From John Mackin (1991-03-06):
duke@0 849 # We in Australia have _never_ referred to DST as `daylight' time.
duke@0 850 # It is called `summer' time. Now by a happy coincidence, `summer'
duke@0 851 # and `standard' happen to start with the same letter; hence, the
duke@0 852 # abbreviation does _not_ change...
duke@0 853 # The legislation does not actually define abbreviations, at least
duke@0 854 # in this State, but the abbreviation is just commonly taken to be the
duke@0 855 # initials of the phrase, and the legislation here uniformly uses
duke@0 856 # the phrase `summer time' and does not use the phrase `daylight
duke@0 857 # time'.
duke@0 858 # Announcers on the Commonwealth radio network, the ABC (for Australian
duke@0 859 # Broadcasting Commission), use the phrases `Eastern Standard Time'
duke@0 860 # or `Eastern Summer Time'. (Note, though, that as I say in the
duke@0 861 # current australasia file, there is really no such thing.) Announcers
duke@0 862 # on its overseas service, Radio Australia, use the same phrases
duke@0 863 # prefixed by the word `Australian' when referring to local times;
duke@0 864 # time announcements on that service, naturally enough, are made in UTC.

duke@0 866 # From Arthur David Olson (1992-03-08):

duke@0 875 # And this government web page lists time zone names and abbreviations:
duke@0 876 # <http://www.bom.gov.au/climate/averages/tables/daysavtm.shtml>
duke@0 877
duke@0 878 # From Paul Eggert (2001-04-05), summarizing a long discussion about "EST"
duke@0 879 # versus "AEST" etc.:
duke@0 880 #
duke@0 881 # I see the following points of dispute:
duke@0 882 #
duke@0 883 # * How important are unique time zone abbreviations?
duke@0 884 #
duke@0 885 # Here I tend to agree with the point (most recently made by Chris
duke@0 886 # Newman) that unique abbreviations should not be essential for proper
duke@0 887 # operation of software. We have other instances of ambiguity
duke@0 888 # (e.g. "IST" denoting both "Israel Standard Time" and "Indian
duke@0 889 # Standard Time"), and they are not likely to go away any time soon.
duke@0 890 # In the old days, some software mistakenly relied on unique
duke@0 891 # abbreviations, but this is becoming less true with time, and I don't
duke@0 892 # think it's that important to cater to such software these days.
duke@0 893 #
duke@0 894 # On the other hand, there is another motivation for unambiguous
duke@0 895 # abbreviations: it cuts down on human confusion. This is
duke@0 896 # particularly true for Australia, where "EST" can mean one thing for
duke@0 897 # time T and a different thing for time T plus 1 second.
duke@0 898 #
duke@0 899 # * Does the relevant legislation indicate which abbreviations should be used?
duke@0 900 #
duke@0 901 # Here I tend to think that things are a mess, just as they are in
duke@0 902 # many other countries. We Americans are currently disagreeing about
duke@0 903 # which abbreviation to use for the newly legislated Chamorro Standard
duke@0 904 # Time, for example.
duke@0 905 #
duke@0 906 # Personally, I would prefer to use common practice; I would like to
duke@0 907 # refer to legislation only for examples of common practice, or as a
duke@0 908 # tiebreaker.
duke@0 909 #
duke@0 910 # * Do Australians more often use "Eastern Daylight Time" or "Eastern
duke@0 911 # Summer Time"? Do they typically prefix the time zone names with
duke@0 912 # the word "Australian"?
duke@0 913 #
duke@0 914 # My own impression is that both "Daylight Time" and "Summer Time" are
duke@0 915 # common and are widely understood, but that "Summer Time" is more
duke@0 916 # popular; and that the leading "A" is also common but is omitted more
duke@0 917 # often than not. I just used AltaVista advanced search and got the
duke@0 918 # following count of page hits:
duke@0 919 #
duke@0 920 # 1,103 "Eastern Summer Time" AND domain:au
duke@0 921 # 971 "Australian Eastern Summer Time" AND domain:au
duke@0 922 # 613 "Eastern Daylight Time" AND domain:au
duke@0 923 # 127 "Australian Eastern Daylight Time" AND domain:au
duke@0 924 #
duke@0 925 # Here "Summer" seems quite a bit more popular than "Daylight",
duke@0 926 # particularly when we know the time zone is Australian and not US,
duke@0 927 # say. The "Australian" prefix seems to be popular for Eastern Summer
duke@0 928 # Time, but unpopular for Eastern Daylight Time.
duke@0 929 #
duke@0 930 # For abbreviations, tools like AltaVista are less useful because of
duke@0 931 # ambiguity. Many hits are not really time zones, unfortunately, and
duke@0 932 # many hits denote US time zones and not Australian ones. But here
duke@0 933 # are the hit counts anyway:
duke@0 934 #
duke@0 935 # 161,304 "EST" and domain:au
duke@0 936 # 25,156 "EDT" and domain:au
duke@0 937 # 18,263 "AEST" and domain:au
duke@0 938 # 10,416 "AEDT" and domain:au
duke@0 939 #
duke@0 940 # 14,538 "CST" and domain:au
duke@0 941 # 5,728 "CDT" and domain:au

duke@0 944 #
duke@0 945 # 7,539 "WST" and domain:au
duke@0 946 # 68 "AWST" and domain:au
duke@0 947 #
duke@0 948 # This data suggest that Australians tend to omit the "A" prefix in
duke@0 949 # practice. The situation for "ST" versus "DT" is less clear, given
duke@0 950 # the ambiguities involved.
duke@0 951 #
duke@0 952 # * How do Australians feel about the abbreviations in the tz database?
duke@0 953 #
duke@0 954 # If you just count Australians on this list, I count 2 in favor and 3
duke@0 955 # against. One of the "against" votes (David Keegel) counseled delay,
duke@0 956 # saying that both AEST/AEDT and EST/EST are widely used and
duke@0 957 # understood in Australia.

duke@0 1228 # Observatories"[1], and in particular the Shrine of Remembrance[2] located
duke@0 1229 # in Melbourne, Australia.
duke@0 1230 #
duke@0 1231 # Apparently the shrine's main purpose is a beam of sunlight which
duke@0 1232 # illuminates a special spot on the floor at the 11th hour of the 11th day
duke@0 1233 # of the 11th month (Remembrance Day) every year in memory of Australia's
duke@0 1234 # fallen WWI soldiers. And if you go there on Nov. 11, at 11am local time,
duke@0 1235 # you will indeed see the sunbeam illuminate the special spot at the
duke@0 1236 # expected time.
duke@0 1237 #
duke@0 1238 # However, that is only because of some special mirror contraption that had
duke@0 1239 # to be employed, since due to daylight savings time, the true solar time of

duke@0 1696 # mapmakers redrew the IDL following the boundary of Kiribati. Even that line
duke@0 1697 # has a rather arbitrary nature. The straight-line boundaries between Pacific
duke@0 1698 # island nations that are shown on many maps are based on an international
duke@0 1699 # convention, but are not legally binding national borders.... The date is
duke@0 1700 # governed by the IDL; therefore, even on the high seas, there may be some
duke@0 1701 # places as late as fourteen hours later than UTC. And, since the IDL is not
duke@0 1702 # an international standard, there are some places on the high seas where the
duke@0 1703 # correct date is ambiguous.

duke@0 1705 # From Wikipedia <http://en.wikipedia.org/wiki/Time_zone> (2005-08-31):
duke@0 1706 # Before 1920, all ships kept local apparent time on the high seas by setting
duke@0 1707 # their clocks at night or at the morning sight so that, given the ship's
duke@0 1708 # speed and direction, it would be 12 o'clock when the Sun crossed the ship's
duke@0 1709 # meridian (12 o'clock = local apparent noon). During 1917, at the
duke@0 1710 # Anglo-French Conference on Time-keeping at Sea, it was recommended that all
duke@0 1711 # ships, both military and civilian, should adopt hourly standard time zones
duke@0 1712 # on the high seas. Whenever a ship was within the territorial waters of any
duke@0 1713 # nation it would use that nation's standard time. The captain was permitted
duke@0 1714 # to change his ship's clocks at a time of his choice following his ship's
duke@0 1715 # entry into another zone time--he often chose midnight. These zones were
duke@0 1716 # adopted by all major fleets between 1920 and 1925 but not by many
duke@0 1717 # independent merchant ships until World War II.
