# 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.)
# From Robert Elz (May 5, 1989):
#
# From next year (1990) NSW will revert to ending DST on the 1st
# Sunday in March (rather than the third, which it appears will
# continue to be what everyone else uses).
