84 |
# Hamilton is the largest, but there is also a Hamilton in Victoria,

684 |
# From John Mackin (1991-03-06):
|
|
|
685 |
# We in Australia have _never_ referred to DST as `daylight' time.
|
|
|
686 |
# It is called `summer' time. Now by a happy coincidence, `summer'
|
|
|
687 |
# and `standard' happen to start with the same letter; hence, the
|
|
|
688 |
# abbreviation does _not_ change...
|
|
|
689 |
# The legislation does not actually define abbreviations, at least
|
|
|
690 |
# in this State, but the abbreviation is just commonly taken to be the
|
|
|
691 |
# initials of the phrase, and the legislation here uniformly uses
|
|
|
692 |
# the phrase `summer time' and does not use the phrase `daylight
|
|
|
693 |
# time'.
|
|
|
694 |
# Announcers on the Commonwealth radio network, the ABC (for Australian
|
|
|
695 |
# Broadcasting Commission), use the phrases `Eastern Standard Time'
|
|
|
696 |
# or `Eastern Summer Time'. (Note, though, that as I say in the
|
|
|
697 |
# current australasia file, there is really no such thing.) Announcers
|
|
|
698 |
# on its overseas service, Radio Australia, use the same phrases
|
|
|
699 |
# prefixed by the word `Australian' when referring to local times;
|
|
|
700 |
# time announcements on that service, naturally enough, are made in UTC.

# From Arthur David Olson (1992-03-08):

|
703 |
# Given the above, what's chosen for year-round use is:
|
|
|
704 |
# CST for any place operating at a GMTOFF of 9:30

706 |

# I recently found this Australian government web page on time zones:
|
|
|
710 |
# <http://www.australia.gov.au/about-australia-13time>

711 |
# And this government web page lists time zone names and abbreviations:

|
|
|
713 |
|
|
|
714 |
# From Paul Eggert (2001-04-05), summarizing a long discussion about "EST"
|
|
|
715 |
# versus "AEST" etc.:
|
|
|
716 |
#
|
|
|
717 |
# I see the following points of dispute:
|
|
|
718 |
#
|
|
|
719 |
# * How important are unique time zone abbreviations?
|
|
|
720 |
#
|
|
|
721 |
# Here I tend to agree with the point (most recently made by Chris
|
|
|
722 |
# Newman) that unique abbreviations should not be essential for proper
|
|
|
723 |
# operation of software. We have other instances of ambiguity
|
|
|
724 |
# (e.g. "IST" denoting both "Israel Standard Time" and "Indian
|
|
|
725 |
# Standard Time"), and they are not likely to go away any time soon.
|
|
|
726 |
# In the old days, some software mistakenly relied on unique
|
|
|
727 |
# abbreviations, but this is becoming less true with time, and I don't
|
|
|
728 |
# think it's that important to cater to such software these days.
|
|
|
729 |
#
|
|
|
730 |
# On the other hand, there is another motivation for unambiguous
|
|
|
731 |
# abbreviations: it cuts down on human confusion. This is
|
|
|
732 |
# particularly true for Australia, where "EST" can mean one thing for
|
|
|
733 |
# time T and a different thing for time T plus 1 second.
|
|
|
734 |
#
|
|
|
735 |
# * Does the relevant legislation indicate which abbreviations should be used?
|
|
|
736 |
#
|
|
|
737 |
# Here I tend to think that things are a mess, just as they are in
|
|
|
738 |
# many other countries. We Americans are currently disagreeing about
|
|
|
739 |
# which abbreviation to use for the newly legislated Chamorro Standard
|
|
|
740 |
# Time, for example.
|
|
|
741 |
#
|
|
|
742 |
# Personally, I would prefer to use common practice; I would like to
|
|
|
743 |
# refer to legislation only for examples of common practice, or as a
|
|
|
744 |
# tiebreaker.
|
|
|
745 |
#
|
|
|
746 |
# * Do Australians more often use "Eastern Daylight Time" or "Eastern
|
|
|
747 |
# Summer Time"? Do they typically prefix the time zone names with
|
|
|
748 |
# the word "Australian"?
|
|
|
749 |
#
|
|
|
750 |
# My own impression is that both "Daylight Time" and "Summer Time" are
|
|
|
751 |
# common and are widely understood, but that "Summer Time" is more
|
|
|
752 |
# popular; and that the leading "A" is also common but is omitted more
|
|
|
753 |
# often than not. I just used AltaVista advanced search and got the
|
|
|
754 |
# following count of page hits:
|
|
|
755 |
#
|
|
|
756 |
# 1,103 "Eastern Summer Time" AND domain:au
|
|
|
757 |
# 971 "Australian Eastern Summer Time" AND domain:au
|
|
|
758 |
# 613 "Eastern Daylight Time" AND domain:au
|
|
|
759 |
# 127 "Australian Eastern Daylight Time" AND domain:au
|
|
|
760 |
#
|
|
|
761 |
# Here "Summer" seems quite a bit more popular than "Daylight",
|
|
|
762 |
# particularly when we know the time zone is Australian and not US,
|
|
|
763 |
# say. The "Australian" prefix seems to be popular for Eastern Summer
|
|
|
764 |
# Time, but unpopular for Eastern Daylight Time.
|
|
|
765 |
#
|
|
|
766 |
# For abbreviations, tools like AltaVista are less useful because of
|
|
|
767 |
# ambiguity. Many hits are not really time zones, unfortunately, and
|
|
|
768 |
# many hits denote US time zones and not Australian ones. But here

# On KQED's "City Arts and Lectures" program last night I heard an
|
|
|
1062 |
# interesting story about daylight savings time. Dr. John Heilbron was
|
|
|
1063 |
# discussing his book "The Sun in the Church: Cathedrals as Solar
|

1064 |
# Observatories"[1], and in particular the Shrine of Remembrance[2] located

1065 |
# in Melbourne, Australia.
|
|

1066 |
#
|
|

1067 |
# Apparently the shrine's main purpose is a beam of sunlight which
|
|
|
1068 |
# illuminates a special spot on the floor at the 11th hour of the 11th day
|
|
|
1069 |
# of the 11th month (Remembrance Day) every year in memory of Australia's
|
|
|
1070 |
# fallen WWI soldiers. And if you go there on Nov. 11, at 11am local time,
|
|
|
1071 |
# you will indeed see the sunbeam illuminate the special spot at the
|
|
|
1072 |
# expected time.
|
|

1073 |
#
|
|
|
1074 |
# However, that is only because of some special mirror contraption that had

1075 |
# to be employed, since due to daylight savings time, the true solar time of
|
|
|
1076 |
# the remembrance moment occurs one hour later (or earlier?). Perhaps

#
|

1524 |
# The International Date Line is not defined by any international standard,
|
|
|
1525 |
# convention, or treaty. Mapmakers are free to draw it as they please.
|
|
|
1526 |
# Reputable mapmakers will simply ensure that every point of land appears on

1527 |
# the correct side of the IDL, according to the date legally observed there.

1528 |
#

1529 |
# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and

|
|
1530 |
# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL
|
|
|
1531 |
# to the east side of the Phoenix and Line Islands), I suppose that most
|
|
|
1532 |
# mapmakers redrew the IDL following the boundary of Kiribati. Even that line
|
|
|
1533 |
# has a rather arbitrary nature. The straight-line boundaries between Pacific
|
|
|
1534 |
# island nations that are shown on many maps are based on an international
|
|
|
1535 |
# convention, but are not legally binding national borders.... The date is
|
|
|
1536 |
# governed by the IDL; therefore, even on the high seas, there may be some
|
|
|
1537 |
# places as late as fourteen hours later than UTC. And, since the IDL is not
|
|
|
1538 |

# Before 1920, all ships kept local apparent time on the high seas by setting
|
|
|
1543 |
# their clocks at night or at the morning sight so that, given the ship's
|
|
|
1544 |
# speed and direction, it would be 12 o'clock when the Sun crossed the ship's
|
|
|
1545 |
# meridian (12 o'clock = local apparent noon). During 1917, at the
|
|
|
1546 |
# Anglo-French Conference on Time-keeping at Sea, it was recommended that all
|
|
|
1547 |
# ships, both military and civilian, should adopt hourly standard time zones
|
|
|
1548 |
# on the high seas. Whenever a ship was within the territorial waters of any
|
|
|
1549 |
# nation it would use that nation's standard time. The captain was permitted

|
|
1550 |
# to change his ship's clocks at a time of his choice following his ship's
|
|
|
1551 |
# entry into another zone time--he often chose midnight. These zones were
