+# From Chris Walton (2006-04-05):
+# Here is a copy of the new official time act ...
+# http://web2.gov.mb.ca/laws/statutes/ccsm/o030e.php
+# The act indicates that daylight savings ends at 2:00am.
+
+# From Rob Douglas (2006-04-06):
+# the old Manitoba Time Act - as amended by Bill 2, assented to
+# March 27, 1987 ... said ...
+# "between two o'clock Central Standard Time in the morning of
+# the first Sunday of April of each year and two o'clock Central
+# Standard Time in the morning of the last Sunday of October next
+# following, one hour in advance of Central Standard Time."...
+# I believe that the English legislation [of the old time act] had =
+# been assented to (March 22, 1967)....
+# Also, as far as I can tell, there was no order-in-council varying
+# the time of Daylight Saving Time for 2005 and so the provisions of
+# the 1987 version would apply - the changeover was at 2:00 Central
+# Standard Time (i.e. not until 3:00 Central Daylight Time).
+
+# From Paul Eggert (2006-04-10):
+# Shanks & Pottenger say Manitoba switched at 02:00 (not 02:00s)
+# starting 1966.  Since 02:00s is clearly correct for 1967 on, assume
+# it was also 02:00s in 1966.
