# 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 Paul Eggert (1995-12-19):
# Shanks reports 2:00 for all autumn changes in Australia and New Zealand.
# Mark Prior <mrp@itd.adelaide.edu.au> 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
# and perhaps the newspaper's `2:00' is referring to standard time.
# For now we'll continue to assume 2:00s for changes since 1960.

# New South Wales
# 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.

# Sources differ on whether DST ended March 6 or March 20 in 1988;
# March 20 (the "confirmed" date) is in the chosen rules.

# # Yancowinna uses Central Standard Time, despite it's location on the

# # are with CST zones, therefore CST is legislated by local government
# # although the switch to Summer Time occurs in line with N.S.W. There have

# Lord Howe Island is located off the New South Wales coast, and is half an
# hour ahead of NSW time.
# From Paul Eggert (1995-12-19):
# For Lord Howe we use Shanks through its time of publication (1991).
# Lord Howe is part of NSW, so we'll guess it has used the same transition
# times as NSW since 1991, even though Shanks writes that Lord Howe went
# with Victoria when NSW and Victoria disagreed in 1982.

# From Paul Eggert (1995-12-19);

# Robert Uzgalis <buz@cs.aukuni.ac.nz> writes that the New Zealand Daylight
# Savings Time Order in Council dated 1990-06-18 specifies 2:00 standard
# time on both the first Sunday in October and the third Sunday in March.
# As with Australia, we'll assume the tradition is 2:00s, not 2:00.

# Howse writes (p 162) that in 1879 the British governor of Fiji
# enacted an ordinance standardizing the islands on +12:00.

# Johnston
# Johnston data is from usno1995.
# Kwajalein
# In comp.risks 14.87 (26 August 1993), Peter Neumann writes:
# I wonder what happened in Kwajalein, where there was NO Friday,
# August 20, 1993. Thursday night at midnight Kwajalein switched sides with
# respect to the International Date Line, to rejoin its fellow islands,
# going from 11:59 p.m. Thursday to 12:00 m. Saturday in a blink.
# N Mariana Is, Guam
# Howse writes (p 162) ``The Spaniards, on the other hand, reached the
# Philippines and the Ladrones from America,'' and implies that the Ladrones
# (now called the Marianas) kept American date for quite some time.
# Ignore this for now, as we have no hard data. See also Asia/Manila.
# Samoa
# Howse writes that in 1879 the King of Samoa decided to change
# ``the date in his kingdom from the Antipodean to the American system,
# ordaining -- by a masterpiece of diplomatic flattery -- that
# the Fourth of July should be celebrated twice in that year.''
