australasia

Attached is what I hope is the final (for spring of 1992 anyway) version of
australasia, incorporating lots of good suggestions and information from
Bradley White and Robert Elz.  The shar file will unpack to two files,
"yearistype.sh" and "australasia"--be sure to make an executable version
of "yearistype.sh" named "yearistype" before running "zic".
On recent-vintage Sun systems, the command
	make yearistype
suffices.  The shell script is needed because South Australia now seems to end
DST at different times in even and odd years.

# NOTES

###############################################################################

# 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 Arthur David Olson (March 8 1992):
# 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 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.

# A recent excerpt from an Australian newspaper...

# Australia/West

# From George Shepherd via Simon Woodhead via Robert Elz (March 6, 1991):
# #  The state of WESTERN AUSTRALIA..  [ Courtesy W.A. dept Premier+Cabinet ]
# #						[ Nov 1990 ]
# #	W.A. suffers from a great deal of public and political opposition to
# #	DST in principle. A bill is brought before parliament in most years, but
# #	usually defeated either in the upper house, or in party caucus

# From John D. Newman via Bradley White (November 2, 1991):
# Western Australia is still on "winter time". Some DH in Sydney
# rang me at home a few days ago at 6.00am. (He had just arrived at
# work at 9.00am.)
# W.A. is switching to Summer Time on Nov 17th just to confuse
# everybody again.

# From Arthur David Olson (March 8, 1992):
# The 1992 ending date used in the rules is a best guess;
# it matches what was used in the past.

# I can certainly confirm for my part that Daylight Saving in NSW did in fact
# end on Sunday, 3 March.  I don't know at what hour, though.  (It surprised
# me.)

# From Bradley White (March 8, 1992):

# From Arthur David Olson (March 8, 1992):
# The rules from version 7.1 follow.

# From Robert Elz (March 6, 1991):
# I believe that the current start date for DST is "lastSun" in Oct...
# that changed Oct 89.  That is, we're back to the
# original rule, and that rule currently applies in all the states
# that have dst, incl Qld.  (Certainly it was true in Vic).

# 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 at 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.
