392# Australia
393
394# From John Mackin (March 6, 1991):
395# We in Australia have _never_ referred to DST as `daylight' time.
396# It is called `summer' time. Now by a happy coincidence, `summer'
397# and `standard' happen to start with the same letter; hence, the
398# abbreviation does _not_ change...
399# The legislation does not actually define abbreviations, at least
400# in this State, but the abbreviation is just commonly taken to be the
401# initials of the phrase, and the legislation here uniformly uses
402# the phrase `summer time' and does not use the phrase `daylight
403# time'.
404# Announcers on the Commonwealth radio network, the ABC (for Australian
405# Broadcasting Commission), use the phrases `Eastern Standard Time'
406# or `Eastern Summer Time'. (Note, though, that as I say in the
407# current australasia file, there is really no such thing.) Announcers
408# on its overseas service, Radio Australia, use the same phrases
409# prefixed by the word `Australian' when referring to local times;
410# time announcements on that service, naturally enough, are made in UTC.
411
412# From Arthur David Olson (March 8 1992):
413# Given the above, what's chosen for year-round use is:
414# CST for any place operating at a GMTOFF of 9:30
415# WST for any place operating at a GMTOFF of 8:00
416# EST for any place operating at a GMTOFF of 10:00

422# # [ Nov 1990 ]
423# # N.T. have never utilised any DST due to sub-tropical/tropical location.

393
394# From John Mackin (March 6, 1991):
395# We in Australia have _never_ referred to DST as `daylight' time.
396# It is called `summer' time. Now by a happy coincidence, `summer'
397# and `standard' happen to start with the same letter; hence, the
398# abbreviation does _not_ change...
399# The legislation does not actually define abbreviations, at least
400# in this State, but the abbreviation is just commonly taken to be the
401# initials of the phrase, and the legislation here uniformly uses
402# the phrase `summer time' and does not use the phrase `daylight
403# time'.
404# Announcers on the Commonwealth radio network, the ABC (for Australian
405# Broadcasting Commission), use the phrases `Eastern Standard Time'
406# or `Eastern Summer Time'. (Note, though, that as I say in the
407# current australasia file, there is really no such thing.) Announcers
408# on its overseas service, Radio Australia, use the same phrases
409# prefixed by the word `Australian' when referring to local times;
410# time announcements on that service, naturally enough, are made in UTC.
411
412# From Arthur David Olson (March 8 1992):
413# Given the above, what's chosen for year-round use is:
414# CST for any place operating at a GMTOFF of 9:30

547# From Bradley White (March 11, 1992):
548# Recent correspondence with a friend in Adelaide
549# contained the following exchange: "Due to the Adelaide Festival,
550# South Australia delays setting back our clocks for a few weeks."
551
552# From Robert Elz (March 13, 1992):
553# I heard that apparently (or at least, it appears that)
554# South Aus will have an extra 3 weeks daylight saving every even
555# numbered year (from 1990). That's when the Adelaide Festival
556# is on...
557
558# From Robert Elz (March 16, 1992, 00:57:07 +1000):
559# DST didn't end in Adelaide today (yesterday)....
560# But whether it's "4th Sunday" or "2nd last Sunday" I have no idea whatever...
561# (it's just as likely to be "the Sunday we pick for this year"...).
562
563# From Bradley White (April 11, 1994):
564# If Sun, 15 March, 1992 was at +1030 as kre asserts, but yet Sun, 20 March,
565# 1994 was at +0930 as John Connolly's customer seems to assert, then I can
566# only conclude that the actual rule is more complicated....

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