Now by a happy coincidence, `summer' 496# and `standard' happen to start with the same letter; hence, the 497# abbreviation does _not_ change... 498# The legislation does not actually define abbreviations, at least 499# in this State, but the abbreviation is just commonly taken to be the 500# initials of the phrase, and the legislation here uniformly uses 501# the phrase `summer time' and does not use the phrase `daylight 502# time'. 503# Announcers on the Commonwealth radio network, the ABC (for Australian 504# Broadcasting Commission), use the phrases `Eastern Standard Time' 505# or `Eastern Summer Time'. (Note, though, that as I say in the 506# current australasia file, there is really no such thing.) Announcers 507# on its overseas service, Radio Australia, use the same phrases 508# prefixed by the word `Australian' when referring to local times; 509# time announcements on that service, naturally enough, are made in UTC. 510 511# From Arthur David Olson (March 8 1992): 512# Given the above, what's chosen for year-round use is: 513# CST for any place operating at a GMTOFF of 9:30 514# WST for any place operating at a GMTOFF of 8:00 515# EST for any place operating at a GMTOFF of 10:00 516 517# From Paul Eggert (1995-12-19): 518# Shanks reports 2:00 for all autumn changes in Australia and New Zealand. 519# Mark Prior <mrp@itd.adelaide.edu.au> writes that his newspaper 520# reports that NSW's fall 1995 change will occur at 2:00, 521# but Robert Elz says it's been 3:00 in Victoria since 1970 522# and perhaps the newspaper's `2:00' is referring to standard time. 523# For now we'll continue to assume 2:00s for changes since 1960. 524 525# From Eric Ulevik <eau@zip.com.au> (1998-01-05): 526# 527# Here are some URLs to Australian time legislation.
