+# 1983-03-20 as well, but that was not successful....

+# From Arthur David Olson (2008-06-30):
+# The www.timeanddate.com article cited by Steffen Thorsen notes that "A

+# From Steffen Thorsen (2008-07-10):
+# According to
+# 
+# http://www.lexpress.mu/display_article.php?news_id=111216
+# 
+# (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.
