+# (in French), Mauritius will start and end their DST a few days earlier
+# than previously announced (2008-11-01 to 2009-03-31).  The new start
+# date is 2008-10-26 at 02:00 and the new end date is 2009-03-27 (no time
+# given, but it is probably at either 2 or 3 wall clock time).
+# 
+# A little strange though, since the article says that they moved the date 
+# to align itself with Europe and USA which also change time on that date, 
+# but that means they have not paid attention to what happened in 
+# USA/Canada last year (DST ends first Sunday in November). I also wonder 
+# why that they end on a Friday, instead of aligning with Europe which 
+# changes two days later.
+
+# From Alex Krivenyshev (2008-07-11):
+# Seems that English language article "The revival of daylight saving
+# time:  Energy conservation?"-# No. 16578 (07/11/2008) was originally
+# published on Monday, June 30, 2008...
+#
+# I guess that article in French "Le gouvernement avance l'introduction
+# de l'heure d'ete" stating that DST in Mauritius starting on October 26
+# and ending on March 27, 2009 is the most recent one.

+# I just now checked Google News for western news sources that talk
+# about China's single time zone, and couldn't find anything before 1986
+# talking about China being in one time zone.  (That article was: Jim

+# I think you're combining two subjects that need to treated 
+# separately: daylight savings (which, you're correct, wasn't 
+# implemented until the 1980s) and the unified time zone centered near 
+# Beijing (which was implemented in 1949). Briefly, there was also a 
+# "Lhasa Time" in Tibet and "Urumqi Time" in Xinjiang. The first was 
+# ceased, and the second eventually recognized (again, in the 1980s).

+# From Paul Schulze (2008-06-24):
+# ...by law number 11.662 of April 24, 2008 (published in the "Diario
+# Oficial da Uniao"...) in Brazil there are changes in the timezones,
+# effective today (00:00am at June 24, 2008) as follows:
+#
+# a) The timezone UTC+5 is e[x]tinguished, with all the Acre state and the
+# part of the Amazonas state that had this timezone now being put to the
+# timezone UTC+4
+# b) The whole Para state now is put at timezone UTC+3, instead of just
+# part of it, as was before.
+#
+# This change follows a proposal of senator Tiao Viana of Acre state, that
+# proposed it due to concerns about open television channels displaying
+# programs inappropriate to youths in the states that had the timezone
+# UTC+5 too early in the night. In the occasion, some more corrections
+# were proposed, trying to unify the timezones of any given state. This
+# change modifies timezone rules defined in decree 2.784 of 18 June,
+# 1913.
+
+# From Rodrigo Severo (2008-06-24):
+# Just correcting the URL:

+# </a>
+#
+# As a result of the above Decree I believe the America/Rio_Branco
+# timezone shall be modified from UTC-5 to UTC-4 and a new timezone shall
+# be created to represent the the west side of the Para State. I
+# suggest this new timezone be called Santarem as the most
+# important/populated city in the affected area.
+#
+# This new timezone would be the same as the Rio_Branco timezone up to
+# the 2008/06/24 change which would be to UTC-3 instead of UTC-4.

+# From Alex Krivenyshev (2008-06-24):
