    62 # Hamilton is the largest, but there is also a Hamilton in Victoria,

   705 # We in Australia have _never_ referred to DST as `daylight' time.
       
   706 # It is called `summer' time.  Now by a happy coincidence, `summer'
       
   707 # and `standard' happen to start with the same letter; hence, the
       
   708 # abbreviation does _not_ change...
       
   709 # The legislation does not actually define abbreviations, at least
       
   710 # in this State, but the abbreviation is just commonly taken to be the
       
   711 # initials of the phrase, and the legislation here uniformly uses
       
   712 # the phrase `summer time' and does not use the phrase `daylight
       
   713 # time'.
       
   714 # Announcers on the Commonwealth radio network, the ABC (for Australian
       
   715 # Broadcasting Commission), use the phrases `Eastern Standard Time'
       
   716 # or `Eastern Summer Time'.  (Note, though, that as I say in the
       
   717 # current australasia file, there is really no such thing.)  Announcers
       
   718 # on its overseas service, Radio Australia, use the same phrases

   733 
       
   734 # From Paul Eggert (2001-04-05), summarizing a long discussion about "EST"
       
   735 # versus "AEST" etc.:
       
   736 #
       
   737 # I see the following points of dispute:
       
   738 #
       
   739 # * How important are unique time zone abbreviations?
       
   740 #
       
   741 #   Here I tend to agree with the point (most recently made by Chris
       
   742 #   Newman) that unique abbreviations should not be essential for proper
       
   743 #   operation of software.  We have other instances of ambiguity
       
   744 #   (e.g. "IST" denoting both "Israel Standard Time" and "Indian
       
   745 #   Standard Time"), and they are not likely to go away any time soon.
       
   746 #   In the old days, some software mistakenly relied on unique
       
   747 #   abbreviations, but this is becoming less true with time, and I don't
       
   748 #   think it's that important to cater to such software these days.
       
   749 #
       
   750 #   On the other hand, there is another motivation for unambiguous
       
   751 #   abbreviations: it cuts down on human confusion.  This is
       
   752 #   particularly true for Australia, where "EST" can mean one thing for
       
   753 #   time T and a different thing for time T plus 1 second.
       
   754 #
       
   755 # * Does the relevant legislation indicate which abbreviations should be used?
       
   756 #
       
   757 #   Here I tend to think that things are a mess, just as they are in
       
   758 #   many other countries.  We Americans are currently disagreeing about
       
   759 #   which abbreviation to use for the newly legislated Chamorro Standard
       
   760 #   Time, for example.
       
   761 #
       
   762 #   Personally, I would prefer to use common practice; I would like to
       
   763 #   refer to legislation only for examples of common practice, or as a
       
   764 #   tiebreaker.
       
   765 #
       
   766 # * Do Australians more often use "Eastern Daylight Time" or "Eastern
       
   767 #   Summer Time"?  Do they typically prefix the time zone names with
       
   768 #   the word "Australian"?
       
   769 #
       
   770 #   My own impression is that both "Daylight Time" and "Summer Time" are
       
   771 #   common and are widely understood, but that "Summer Time" is more
       
   772 #   popular; and that the leading "A" is also common but is omitted more
       
   773 #   often than not.  I just used AltaVista advanced search and got the
       
   774 #   following count of page hits:
       
   775 #
       
   776 #     1,103 "Eastern Summer Time" AND domain:au
       
   777 #       971 "Australian Eastern Summer Time" AND domain:au
       
   778 #       613 "Eastern Daylight Time" AND domain:au
       
   779 #       127 "Australian Eastern Daylight Time" AND domain:au
       
   780 #
       
   781 #   Here "Summer" seems quite a bit more popular than "Daylight",
       
   782 #   particularly when we know the time zone is Australian and not US,
       
   783 #   say.  The "Australian" prefix seems to be popular for Eastern Summer
       
   784 #   Time, but unpopular for Eastern Daylight Time.
       
   785 #
       
   786 #   For abbreviations, tools like AltaVista are less useful because of
       
   787 #   ambiguity.  Many hits are not really time zones, unfortunately, and
       
   788 #   many hits denote US time zones and not Australian ones.  But here
       
   789 #   are the hit counts anyway:

   803 #
       
   804 #   This data suggest that Australians tend to omit the "A" prefix in
       
   805 #   practice.  The situation for "ST" versus "DT" is less clear, given
       
   806 #   the ambiguities involved.
       
   807 #
       
   808 # * How do Australians feel about the abbreviations in the tz database?
       
   809 #
       
   810 #   If you just count Australians on this list, I count 2 in favor and 3

  1561 # From Wikipedia <http://en.wikipedia.org/wiki/Time_zone> (2005-08-31):
       
  1562 # Before 1920, all ships kept local apparent time on the high seas by setting
       
  1563 # their clocks at night or at the morning sight so that, given the ship's
       
  1564 # speed and direction, it would be 12 o'clock when the Sun crossed the ship's
       
  1565 # meridian (12 o'clock = local apparent noon).  During 1917, at the
       
  1566 # Anglo-French Conference on Time-keeping at Sea, it was recommended that all
       
  1567 # ships, both military and civilian, should adopt hourly standard time zones
       
  1568 # on the high seas.  Whenever a ship was within the territorial waters of any
       
  1569 # nation it would use that nation's standard time.  The captain was permitted
       
  1570 # to change his ship's clocks at a time of his choice following his ship's
       
  1571 # entry into another zone time--he often chose midnight.  These zones were
       
  1572 # adopted by all major fleets between 1920 and 1925 but not by many
       
  1573 # independent merchant ships until World War II.
