|
|
# Queensland ceased to.
|
|
#
|
|
# From Paul Eggert (1996-11-22):
|
|
# IATA SSIM (1993-02/1994-09) say that the Holiday Islands (Hayman, Lindeman,
|
|
# Hamilton) observed DST for two years after the rest of Queensland stopped.
|
|
# Hamilton is the largest, but there is also a Hamilton in Victoria,
|
|
# so use Lindeman.

|
|
# Australia's Daylight Saving Times
|
|
# </a>, by Margaret Turner, summarizes daylight saving issues in Australia.
|
|
|
|
# From John Mackin (1991-03-06):
|
|
# We in Australia have _never_ referred to DST as `daylight' time.
|
|
# It is called `summer' time. Now by a happy coincidence, `summer'
|
|
# and `standard' happen to start with the same letter; hence, the
|
|
# abbreviation does _not_ change...
|
|
# The legislation does not actually define abbreviations, at least
|
|
# in this State, but the abbreviation is just commonly taken to be the
|
|
# initials of the phrase, and the legislation here uniformly uses
|
|
# the phrase `summer time' and does not use the phrase `daylight
|
|
# time'.
|
|
# Announcers on the Commonwealth radio network, the ABC (for Australian
|
|
# Broadcasting Commission), use the phrases `Eastern Standard Time'
|
|
# or `Eastern Summer Time'. (Note, though, that as I say in the
|
|
# current australasia file, there is really no such thing.) Announcers
|
|
# on its overseas service, Radio Australia, use the same phrases
|
|
# prefixed by the word `Australian' when referring to local times;
|
|
# time announcements on that service, naturally enough, are made in UTC.
|
|
|
|
# From Arthur David Olson (1992-03-08):
|
|
# Given the above, what's chosen for year-round use is:
|
|
# CST for any place operating at a GMTOFF of 9:30
|
|
# WST for any place operating at a GMTOFF of 8:00
|
|
# EST for any place operating at a GMTOFF of 10:00
|
|
|
|
# From Paul Eggert (2001-04-05), summarizing a long discussion about "EST"
|
|
# versus "AEST" etc.:
|
|
#
|
|
# I see the following points of dispute:
|
|
#
|
|
# * How important are unique time zone abbreviations?
|
|
#
|
|
# Here I tend to agree with the point (most recently made by Chris
|
|
# Newman) that unique abbreviations should not be essential for proper
|
|
# operation of software. We have other instances of ambiguity
|
|
# (e.g. "IST" denoting both "Israel Standard Time" and "Indian
|
|
# Standard Time"), and they are not likely to go away any time soon.
|
|
# In the old days, some software mistakenly relied on unique
|
|
# abbreviations, but this is becoming less true with time, and I don't
|
|
# think it's that important to cater to such software these days.
|
|
#
|
|
# On the other hand, there is another motivation for unambiguous
|
|
# abbreviations: it cuts down on human confusion. This is
|
|
# particularly true for Australia, where "EST" can mean one thing for
|
|
# time T and a different thing for time T plus 1 second.
|
|
#
|
|
# * Does the relevant legislation indicate which abbreviations should be used?
|
|
#
|
|
# Here I tend to think that things are a mess, just as they are in
|
|
# many other countries. We Americans are currently disagreeing about
|
|
# which abbreviation to use for the newly legislated Chamorro Standard
|
|
# Time, for example.
|
|
#
|
|
# Personally, I would prefer to use common practice; I would like to
|
|
# refer to legislation only for examples of common practice, or as a
|
|
# tiebreaker.
|
|
#
|
|
# * Do Australians more often use "Eastern Daylight Time" or "Eastern
|
|
# Summer Time"? Do they typically prefix the time zone names with
|
|
# the word "Australian"?
|
|
#
|
|
# My own impression is that both "Daylight Time" and "Summer Time" are
|
|
# common and are widely understood, but that "Summer Time" is more
|
|
# popular; and that the leading "A" is also common but is omitted more
|
|
# often than not. I just used AltaVista advanced search and got the
|
|
# following count of page hits:
|
|
#
|
|
# 1,103 "Eastern Summer Time" AND domain:au
|
|
# 971 "Australian Eastern Summer Time" AND domain:au
|
|
# 613 "Eastern Daylight Time" AND domain:au
|
|
# 127 "Australian Eastern Daylight Time" AND domain:au
|
|
#
|
|
# Here "Summer" seems quite a bit more popular than "Daylight",
|
|
# particularly when we know the time zone is Australian and not US,
|
|
# say. The "Australian" prefix seems to be popular for Eastern Summer
|
|
# Time, but unpopular for Eastern Daylight Time.
|
|
#
|
|
# For abbreviations, tools like AltaVista are less useful because of
|
|
# ambiguity. Many hits are not really time zones, unfortunately, and
|
|
# many hits denote US time zones and not Australian ones. But here
|
|
# are the hit counts anyway:
|
|
#
|
|
# 161,304 "EST" and domain:au
|
|
# 25,156 "EDT" and domain:au
|
|
# 18,263 "AEST" and domain:au
|
|
# 10,416 "AEDT" and domain:au
|
|
#
|
|
# 14,538 "CST" and domain:au
|
|
# 5,728 "CDT" and domain:au
|
|
# 176 "ACST" and domain:au
|
|
# 29 "ACDT" and domain:au
|
|
#
|
|
# 7,539 "WST" and domain:au
|
|
# 68 "AWST" and domain:au
|
|
#
|
|
# This data suggest that Australians tend to omit the "A" prefix in
|
|
# practice. The situation for "ST" versus "DT" is less clear, given
|
|
# the ambiguities involved.
|
|
#
|
|
# * How do Australians feel about the abbreviations in the tz database?
|
|
#
|
|
# If you just count Australians on this list, I count 2 in favor and 3
|
|
# against. One of the "against" votes (David Keegel) counseled delay,
|
|
# saying that both AEST/AEDT and EST/EST are widely used and
|
|
# understood in Australia.
|
|
|
|
# From Paul Eggert (1995-12-19):
|
|
# Shanks reports 2:00 for all autumn changes in Australia and New Zealand.
|
|
# Mark Prior writes that his newspaper
|
|
# reports that NSW's fall 1995 change will occur at 2:00,
|
|
# but Robert Elz says it's been 3:00 in Victoria since 1970
|
|
# and perhaps the newspaper's `2:00' is referring to standard time.
|
|
# For now we'll continue to assume 2:00s for changes since 1960.

|
|
# The most interesting region I have found consists of three towns on the

|
# southern coast of Australia, population 10 at last report, along with
|
|
# 50,000 sheep, about 100 kilometers long and 40 kilometers into the
|
|
# continent. The primary town is Madura, with the other towns being
|
|
# Mundrabilla and Eucla. According to the sheriff of Madura, the
|
|
# residents got tired of having to change the time so often, as they are
|
|
# located in a strip overlapping the border of South Australia and Western
|
|
# Australia. South Australia observes daylight saving time; Western
|
|
# Australia does not. The two states are one and a half hours apart. The
|
|
# residents decided to forget about this nonsense of changing the clock so
|
|
# much and set the local time 20 hours and 45 minutes from the
|
|
# international date line, or right in the middle of the time of South
|
|
# Australia and Western Australia. As it only affects about 10 people and
|
|
# tourists staying at the Madura Motel, it has never really made as big an
|
|
# impact as Broken Hill. However, as tourist visiting there or anyone
|
|
# calling the local sheriff will attest, they do keep time in this way.

# On KQED's "City Arts and Lectures" program last night I heard an

# interesting story about daylight savings time. Dr. John Heilbron was
|
|
# discussing his book "The Sun in the Church: Cathedrals as Solar
|
|
# Observatories"[1], and in particular the Shrine of Remembrance[2] located
|
|
# in Melbourne, Australia.
|
|
#
|
|
# Apparently the shrine's main purpose is a beam of sunlight which
|
|
# illuminates a special spot on the floor at the 11th hour of the 11th day
|
|
# of the 11th month (Remembrance Day) every year in memory of Australia's
|
|
# fallen WWI soldiers. And if you go there on Nov. 11, at 11am local time,
|
|
# you will indeed see the sunbeam illuminate the special spot at the
|
|
# expected time.
|
|
#
|
|
# However, that is only because of some special mirror contraption that had
|
|
# to be employed, since due to daylight savings time, the true solar time of
|
|
# the remembrance moment occurs one hour later (or earlier?). Perhaps
|
|
# someone with more information on this jury-rig can tell us more.

# In Australia, time is not legislated federally, but rather by the

|
|
# How Tonga became `The Land where Time Begins'
|
|
# </a>:
|
|
|
|
# Until 1941 Tonga maintained a standard time 50 minutes ahead of NZST
|
|
# 12 hours and 20 minutes ahead of GMT. When New Zealand adjusted its
|
|
# standard time in 1940s, Tonga had the choice of subtracting from its
|
|
# local time to come on the same standard time as New Zealand or of
|
|
# advancing its time to maintain the differential of 13 degrees
|
|
# (approximately 50 minutes ahead of New Zealand time).
|
|
#
|
|
# Because His Majesty King Taufa'ahau Tupou IV, then Crown Prince
|
|
# Tungi, preferred to ensure Tonga's title as the land where time
|
|
# begins, the Legislative Assembly approved the latter change.
|
|
#
|
|
# But some of the older, more conservative members from the outer
|
|
# islands objected. "If at midnight on Dec. 31, we move ahead 40
|
|
# minutes, as your Royal Highness wishes, what becomes of the 40
|
|
# minutes we have lost?"
|
|
#
|
|
# The Crown Prince, presented an unanswerable argument: "Remember that
|
|
# on the World Day of Prayer, you would be the first people on Earth
|
|
# to say your prayers in the morning."
|
|
|
|
# From Paul Eggert (1999-08-12):

# Shanks says the transition was on 1968-10-01; go with Mundell.

|
# From Eric Ulevik (1999-05-03):

# The International Date Line
|
|
|
|
# From Gwillim Law (2000-01-03):
|
|
#
|
|
# The International Date Line is not defined by any international standard,
|
|
# convention, or treaty. Mapmakers are free to draw it as they please.
|
|
# Reputable mapmakers will simply ensure that every point of land appears on
|
|
# the correct side of the IDL, according to the date legally observed there.
|
|
#
|
|
# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and
|
|
# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL
|
|
# to the east side of the Phoenix and Line Islands), I suppose that most
|
|
# mapmakers redrew the IDL following the boundary of Kiribati. Even that line
|
|
# has a rather arbitrary nature. The straight-line boundaries between Pacific
|
|
# island nations that are shown on many maps are based on an international
|
|
# convention, but are not legally binding national borders.
|
|
#
|
|
# An Anglo-French Conference on Time-Keeping at Sea (June, 1917) agreed that
|
|
# legal time on the high seas would be zone time, i.e., the standard time at
|
|
# the nearest meridian that is a multiple of fifteen degrees. The date is
|
|
# governed by the IDL; therefore, even on the high seas, there may be some
|
|
# places as late as fourteen hours later than UTC. And, since the IDL is not
|
|
# an international standard, there are some places on the high seas where the
|
|
# correct date is ambiguous.
