+# 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

+# 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

+# 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
