# Australia
# From John Mackin (March 6, 1991):
# 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 George Shepherd via Simon Woodhead via Robert Elz (March 6, 1991):
# # The NORTHERN TERRITORY.. [ Courtesy N.T. Dept of the Chief Minister ]
# # [ Nov 1990 ]
# # N.T. have never utilised any DST due to sub-tropical/tropical location.

# From Arthur David Olson:
# New South Wales and subjurisdictions have their own ideas of a fun time.
# Based on law library research by John Mackin (john@basser.cs.su.oz),
# who notes:
# In Australia, time is not legislated federally, but rather by the
# individual states. Thus, while such terms as ``Eastern Standard Time''
# [I mean, of course, Australian EST, not any other kind] are in common
# use, _they have NO REAL MEANING_, as they are not defined in the
# legislation. This is very important to understand.
# I have researched New South Wales time only; . . .I hope that perhaps a
# resident of each state could be found to do it for their own state.
# (And I can guarantee that Victoria and NSW are different, so the link
# between them in the current australasia file must be broken.)
