Greg Lehey d022814b8f Add $FreeBSD$ 
Correct the date on which DST begins in Victoria and New South Wales
in the year 2000: as the result of some local function in Sydney, DST
will begin on Sunday, 27 August instead of Sunday, 29 Cotober.

This change had already been made, but the date was incorrectly
specified as (Saturday) 26 August.

# From Alex Livingston <alex@agsm.unsw.edu.au> (1996-11-01):
# I have heard or read more than once that some resort islands off the coast
# of Queensland chose to keep observing daylight-saving time even after
# Queensland ceased to.
#
# From Paul Eggert (1996-11-22):
# IATA SSIM (1993-02/1994-09) say that the Holiday Islands (Hayman, Lindeman,
# Hamilton) observed DST for two years after the rest of Queensland stopped.
# Hamilton is the largest, but there is also a Hamilton in Victoria,
# so use Lindeman.

# NOTES
# This data is by no means authoritative; if you think you know better,
# go ahead and edit the file (and please send any changes to
# tz@elsie.nci.nih.gov for general use in the future).
# From Paul Eggert <eggert@twinsun.com> (1996-11-22):
# A good source for time zone historical data outside the U.S. is
# Thomas G. Shanks, The International Atlas (4th edition),
# San Diego: ACS Publications, Inc. (1995).
#
# Gwillim Law <LAW@encmail.encompass.com> writes that a good source
# for recent time zone data is the International Air Transport
# Association's Standard Schedules Information Manual (IATA SSIM),
# published semiannually. Law sent in several helpful summaries
# of the IATA's data after 1990.
#
# Except where otherwise noted, Shanks is the source for entries through 1990,
# and IATA SSIM is the source for entries after 1990.
#
# Another source occasionally used is Edward W. Whitman, World Time Differences,
# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
# I found in the UCLA library.
#
# A reliable and entertaining source about time zones is

# Australia
# From John Mackin (1991-03-06):
# 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

# EST for any place operating at a GMTOFF of 10:00

# 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
