+# From Mark Brader (2003-07-26):

+# the city of Moose Jaw [Saskatchewan] has acted on its own hook."
+# DST in Moose Jaw began on Saturday, 1912-06-01 (no time mentioned:
+# presumably late evening, as below), and would run until "the end of
+# the summer".  The discrepancy between municipal time and railroad
+# time was noted.
