australasia zoneinfo

I have just modified our Australasia zoneinfo file to take account of changes in the NSW rule, and have incorporated changes distributed from Queensland and South Australia over the Australian news recently. I have also added code for Lord Howe Island (perhaps not in the most efficient manner possible). Lord Howe maintains GMT+10:30 when the New South Wales mainland is observing GMT+10:00. When the mainland moves to daylight saving time, it adopts the same time, namely GMT+11:00. So its "saving" is only 30 minutes. My complete file follows: # @(#)australasia 4.1+ (daved mods) # Incorporates updates for Australia from Robert Elz' australia 1.1 # and further updates from the Australian consulate. # Australian Data (for states with DST), standard rules # Includes shift in 1987 to follow Vic/NSW rules for ending DST, # and shift in 1986 to start DST earlier. # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S Rule Oz 1971 1985 - Oct lastSun 2:00 1:00 - Rule Oz 1986 max - Oct Sun<=24 2:00 1:00 - Rule Oz 1972 only - Feb 27 3:00 0 - Rule Oz 1973 1986 - Mar Sun>=1 3:00 0 - Rule Oz 1987 max - Mar Sun<=21 3:00 0 - # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone Australia/Tasmania 10:00 Oz EST Zone Australia/North 9:30 - CST # No DST here Zone Australia/West 8:00 - WST # No DST here Zone Australia/South 9:30 SA CST # The government seems to change things by regulation, not by changing the act. # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S Rule SA 1971 1985 - Oct lastSun 2:00 1:00 - Rule SA 1972 1985 - Mar Sun>=1 3:00 0 - Rule SA 1986 only - Mar 16 3:00 0 - Rule SA 1986 only - Oct 19 2:00 1:00 - Rule SA 1987 only - Mar 15 3:00 0 - Rule SA 1987 max - Oct lastSun 2:00 1:00 - Rule SA 1988 only - Mar 20 3:00 0 - Rule SA 1989 max - Mar Sun<=21 3:00 0 - # Victoria jumped to a later ending date for DST in 1986 rather than 1987.

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.
