 # The transition dates (and times) are guesses.
 
+# From Matt Johnson (2015-09-21):
+# Fort Nelson, BC, Canada will cancel DST this year.  So while previously they
+# were aligned with America/Vancouver, they're now aligned with
+# America/Dawson_Creek.

+#
+# From Tim Parenti (2015-09-23):
+# This requires a new zone for the Northern Rockies Regional Municipality,
+# America/Fort_Nelson.  The resolution of 2014-12-08 was reached following a
+# 2014-11-15 poll with nearly 75% support.  Effectively, the municipality has
+# been on MST (-0700) like Dawson Creek since it advanced its clocks on
+# 2015-03-08.
+#
+# From Paul Eggert (2015-09-23):
+# Shanks says Fort Nelson did not observe DST in 1946, unlike Vancouver.
