547# Australia
548
549# From John Mackin (March 6, 1991):
550# We in Australia have _never_ referred to DST as `daylight' time.
551# It is called `summer' time. Now by a happy coincidence, `summer'
552# and `standard' happen to start with the same letter; hence, the
553# abbreviation does _not_ change...
554# The legislation does not actually define abbreviations, at least
555# in this State, but the abbreviation is just commonly taken to be the
556# initials of the phrase, and the legislation here uniformly uses
557# the phrase `summer time' and does not use the phrase `daylight
558# time'.
559# Announcers on the Commonwealth radio network, the ABC (for Australian
560# Broadcasting Commission), use the phrases `Eastern Standard Time'
561# or `Eastern Summer Time'. (Note, though, that as I say in the
562# current australasia file, there is really no such thing.) Announcers
563# on its overseas service, Radio Australia, use the same phrases
564# prefixed by the word `Australian' when referring to local times;
565# time announcements on that service, naturally enough, are made in UTC.
566
567# From Arthur David Olson (March 8 1992):
568# Given the above, what's chosen for year-round use is:
569# CST for any place operating at a GMTOFF of 9:30
570# WST for any place operating at a GMTOFF of 8:00
571# EST for any place operating at a GMTOFF of 10:00
572
573# From Paul Eggert (1995-12-19):
574# Shanks reports 2:00 for all autumn changes in Australia and New Zealand.
575# Mark Prior <mrp@itd.adelaide.edu.au> writes that his newspaper
576# reports that NSW's fall 1995 change will occur at 2:00,
577# but Robert Elz says it's been 3:00 in Victoria since 1970
578# and perhaps the newspaper's `2:00' is referring to standard time.
579# For now we'll continue to assume 2:00s for changes since 1960.

876# Elz says "no guarantees"
877
878# From Mark Davies (October 3, 1990):
879# the 1989/90 year was a trial of an extended "daylight saving" period.
880# This trial was deemed successful and the extended period adopted for
881# subsequent years (with the addition of a further week at the start).

902# From Paul Eggert (1995-12-19);
903# Shanks reports 2:00 for all autumn changes in Australia and New Zealand.
904# Robert Uzgalis <buz@cs.aukuni.ac.nz> writes that the New Zealand Daylight
905# Savings Time Order in Council dated 1990-06-18 specifies 2:00 standard
906# time on both the first Sunday in October and the third Sunday in March.
907# As with Australia, we'll assume the tradition is 2:00s, not 2:00.

547# Australia
548
549# From John Mackin (March 6, 1991):
550# We in Australia have _never_ referred to DST as `daylight' time.
551# It is called `summer' time. Now by a happy coincidence, `summer'
552# and `standard' happen to start with the same letter; hence, the
553# abbreviation does _not_ change...
554# The legislation does not actually define abbreviations, at least
555# in this State, but the abbreviation is just commonly taken to be the
556# initials of the phrase, and the legislation here uniformly uses
557# the phrase `summer time' and does not use the phrase `daylight
558# time'.
559# Announcers on the Commonwealth radio network, the ABC (for Australian
560# Broadcasting Commission), use the phrases `Eastern Standard Time'
561# or `Eastern Summer Time'. (Note, though, that as I say in the
562# current australasia file, there is really no such thing.) Announcers
563# on its overseas service, Radio Australia, use the same phrases
564# prefixed by the word `Australian' when referring to local times;
565# time announcements on that service, naturally enough, are made in UTC.
566
567# From Arthur David Olson (March 8 1992):
568# Given the above, what's chosen for year-round use is:
569# CST for any place operating at a GMTOFF of 9:30
570# WST for any place operating at a GMTOFF of 8:00
571# EST for any place operating at a GMTOFF of 10:00
572
573# From Paul Eggert (1995-12-19):
574# Shanks reports 2:00 for all autumn changes in Australia and New Zealand.
575# Mark Prior <mrp@itd.adelaide.edu.au> writes that his newspaper
576# reports that NSW's fall 1995 change will occur at 2:00,
577# but Robert Elz says it's been 3:00 in Victoria since 1970
578# and perhaps the newspaper's `2:00' is referring to standard time.
579# For now we'll continue to assume 2:00s for changes since 1960.

800# From Arthur David Olson:
801# New South Wales and subjurisdictions have their own ideas of a fun time.
802# Based on law library research by John Mackin (john@basser.cs.su.oz),
803# who notes:
804# In Australia, time is not legislated federally, but rather by the
805# individual states. Thus, while such terms as ``Eastern Standard Time''
806# [I mean, of course, Australian EST, not any other kind] are in common
807# use, _they have NO REAL MEANING_, as they are not defined in the
808# legislation. This is very important to understand.
809# I have researched New South Wales time only...

831# Sources differ on whether DST ended March 6 or March 20 in 1988;
832# March 20 (the "confirmed" date) is in the chosen rules.
833
834# From Bradley White (1995-05-20):

864# Lord Howe Island is located off the New South Wales coast, and is half an

866
867# From Paul Eggert (1995-12-19):
868# For Lord Howe we use Shanks through its time of publication (1991).
869# Lord Howe is part of NSW, so we'll guess it has used the same transition
870# times as NSW since 1991, even though Shanks writes that Lord Howe went
871# with Victoria when NSW and Victoria disagreed in 1982.

878# From Mark Davies (October 3, 1990):
879# the 1989/90 year was a trial of an extended "daylight saving" period.

902# From Paul Eggert (1995-12-19);
903# Shanks reports 2:00 for all autumn changes in Australia and New Zealand.
