# 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):
# From Arthur David Olson (1992-03-08):
# 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 (2001-04-05), summarizing a long discussion about "EST"
# versus "AEST" etc.:
#
# I see the following points of dispute:
#
# * How important are unique time zone abbreviations?
#
# Here I tend to agree with the point (most recently made by Chris
# Newman) that unique abbreviations should not be essential for proper
# operation of software. We have other instances of ambiguity
# (e.g. "IST" denoting both "Israel Standard Time" and "Indian
# Standard Time"), and they are not likely to go away any time soon.
# In the old days, some software mistakenly relied on unique
# abbreviations, but this is becoming less true with time, and I don't
# think it's that important to cater to such software these days.
#
# On the other hand, there is another motivation for unambiguous
# abbreviations: it cuts down on human confusion. This is
# particularly true for Australia, where "EST" can mean one thing for
# time T and a different thing for time T plus 1 second.
#
# * Does the relevant legislation indicate which abbreviations should be used?
#
# Here I tend to think that things are a mess, just as they are in
# many other countries. We Americans are currently disagreeing about
# which abbreviation to use for the newly legislated Chamorro Standard
# Time, for example.
#
# Personally, I would prefer to use common practice; I would like to
# refer to legislation only for examples of common practice, or as a
# tiebreaker.
#
# * Do Australians more often use "Eastern Daylight Time" or "Eastern
# Summer Time"? Do they typically prefix the time zone names with
# the word "Australian"?
#
# My own impression is that both "Daylight Time" and "Summer Time" are
# common and are widely understood, but that "Summer Time" is more
# popular; and that the leading "A" is also common but is omitted more
# often than not. I just used AltaVista advanced search and got the
# following count of page hits:
#
# 1,103 "Eastern Summer Time" AND domain:au
# 971 "Australian Eastern Summer Time" AND domain:au
# 613 "Eastern Daylight Time" AND domain:au
# 127 "Australian Eastern Daylight Time" AND domain:au
#
# Here "Summer" seems quite a bit more popular than "Daylight",
# particularly when we know the time zone is Australian and not US,
# say. The "Australian" prefix seems to be popular for Eastern Summer
# Time, but unpopular for Eastern Daylight Time.
#
# For abbreviations, tools like AltaVista are less useful because of
# ambiguity. Many hits are not really time zones, unfortunately, and
# many hits denote US time zones and not Australian ones. But here
# are the hit counts anyway:
#
# 161,304 "EST" and domain:au
# 25,156 "EDT" and domain:au
# 18,263 "AEST" and domain:au
# 10,416 "AEDT" and domain:au
#
# 14,538 "CST" and domain:au
# 5,728 "CDT" and domain:au
# 176 "ACST" and domain:au
# 29 "ACDT" and domain:au
#
# 7,539 "WST" and domain:au
# 68 "AWST" and domain:au
#
# This data suggest that Australians tend to omit the "A" prefix in
# practice. The situation for "ST" versus "DT" is less clear, given
# the ambiguities involved.
#
# * How do Australians feel about the abbreviations in the tz database?
#
# If you just count Australians on this list, I count 2 in favor and 3
# against. One of the "against" votes (David Keegel) counseled delay,
# saying that both AEST/AEDT and EST/EST are widely used and
# understood in Australia.

# On KQED's "City Arts and Lectures" program last night I heard an
# interesting story about daylight savings time. Dr. John Heilbron was
# discussing his book "The Sun in the Church: Cathedrals as Solar
# Observatories"[1], and in particular the Shrine of Remembrance[2] located
# in Melbourne, Australia.
#
# Apparently the shrine's main purpose is a beam of sunlight which
# illuminates a special spot on the floor at the 11th hour of the 11th day
# of the 11th month (Remembrance Day) every year in memory of Australia's
# fallen WWI soldiers. And if you go there on Nov. 11, at 11am local time,
# you will indeed see the sunbeam illuminate the special spot at the
# expected time.
#
# However, that is only because of some special mirror contraption that had
# to be employed, since due to daylight savings time, the true solar time of
# the remembrance moment occurs one hour later (or earlier?). Perhaps
# someone with more information on this jury-rig can tell us more.
