+# predecessor. The final reference is to the current Interpretation Act
+# authorizing and resulting from these regulatory changes.
+#
+# Only recent regulations were retrievable via Yukon government site search or
+# index, and only some via Canadian legal sources. Other sources used include
+# articles titled "Standard Time and Time Zones in Canada" from JRASC via ADS
+# Abstracts, cited by ADO for 1932 ..., and updated versions from 1958 and
+# 1970 quoted below; each article includes current extracts from provincial
+# and territorial ST and DST regulations at the end, summaries and details of
+# standard times and daylight saving time at many locations across Canada,
+# with time zone maps, tables and calculations for Canadian Sunrise, Sunset,
+# and LMST; they also cover many countries and global locations, with a chart
+# and table showing current Universal Time offsets, and may be useful as
+# another source of information for 1970 and earlier.
