# I have heard or read more than once that some resort islands off the coast

# 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.

# International Date Line Bill 2011

#
|
# AN ACT to provide for the change to standard time in Samoa and to make

|
#
|
# 1. Short title and commencement-(1) This Act may be cited as the

|
# commences at 12 o'clock midnight, on Thursday 29th December 2011. (3)

|
# [snip]
|
#
|
# 3. Interpretation - [snip] "Samoa standard time" in this Act and any
|
# other statute of Samoa which refers to 'Samoa standard time' means the
|
# time 13 hours in advance of Co-ordinated Universal Time.
|
#
|
# 4. Samoa standard time - (1) Upon the commencement of this Act, Samoa
|
# standard time shall be set at 13 hours in advance of Co-ordinated
|
# Universal Time for the whole of Samoa. (2) All references to Samoa's
|
# time zone and to Samoa standard time in Samoa in all legislation and

# Samoa standard time as provided for in this Act. (3) Nothing in this

|
|
# 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 Chuck Soper (2006-06-01):
|
# I recently found this Australian government web page on time zones:
|
# <http://www.australia.gov.au/about-australia-13time>
|
# And this government web page lists time zone names and abbreviations:
|
# <http://www.bom.gov.au/climate/averages/tables/daysavtm.shtml>
|
|
# 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 & Pottenger report 2:00 for all autumn changes in Australia and NZ.
|
# 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

# 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

# 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

# ... it was just on four years ago that I drove along the Eyre Highway,

# which passes through eastern Western Australia close to the southern

# coast of the continent.
|
#
|
# I paid particular attention to the time kept there. There can be no
|
# dispute that UTC+08:45 was considered "the time" from the border
|
# village just inside the border with South Australia to as far west
|
# as just east of Caiguna. There can also be no dispute that Eucla is
|
# the largest population centre in this zone....
|
#
|
# Now that Western Australia is observing daylight saving, the

|
# (2006-12-09):

# From James Lonergan, Secretary, Lord Howe Island Board (2000-01-27):
|
# Lord Howe Island summer time in 2000/2001 will commence on the same
|
# date as the rest of NSW (i.e. 2000-08-27). For your information the
|
# Lord Howe Island Board (controlling authority for the Island) is
|
# seeking the community's views on various options for summer time
|
# arrangements on the Island, e.g. advance clocks by 1 full hour
|
# instead of only 30 minutes. [Dependent] on the wishes of residents
|
# the Board may approach the NSW government to change the existing
|
# arrangements. The starting date for summer time on the Island will
|
# however always coincide with the rest of NSW.
|
|
# From James Lonergan, Secretary, Lord Howe Island Board (2000-10-25):
|
# Lord Howe Island advances clocks by 30 minutes during DST in NSW and retards
|
# clocks by 30 minutes when DST finishes. Since DST was most recently
|
# introduced in NSW, the "changeover" time on the Island has been 02:00 as
|
# shown on clocks on LHI. I guess this means that for 30 minutes at the start
|
# of DST, LHI is actually 1 hour ahead of the rest of NSW.

|
# <a href="http://www.tongatapu.net.to/tonga/homeland/timebegins.htm">
|
# 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 (2006-03-22):
|
# Shanks & Pottenger say the transition was on 1968-10-01; go with Mundell.
|
|
# From Eric Ulevik (1999-05-03):
|
# Tonga's director of tourism, who is also secretary of the National Millenium
|
# Committee, has a plan to get Tonga back in front.
|
# He has proposed a one-off move to tropical daylight saving for Tonga from
|
# October to March, which has won approval in principle from the Tongan

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