+# Fort Pierre is technically located in the Mountain time zone as is
+# the rest of Stanley County. Most of Stanley County and Fort Pierre
+# uses the Central time zone due to doing most of their business in

+# From Paul Eggert (2016-08-20):
+# In early February 1948, in response to California's electricity shortage,
+# PG&E changed power frequency from 60 to 59.5 Hz during daylight hours,
+# causing electric clocks to lose six minutes per day. (This did not change
+# legal time, and is not part of the data here.) See:
+# Ross SA. An energy crisis from the past: Northern California in 1948.
+# Working Paper No. 8, Institute of Governmental Studies, UC Berkeley,
+# 1973-11. http://escholarship.org/uc/item/8x22k30c
+#
+# In another measure to save electricity, DST was instituted from 1948-03-14
+# at 02:01 to 1949-01-16 at 02:00, with the governor having the option to move
+# the fallback transition earlier. See pages 3-4 of:
+# http://clerk.assembly.ca.gov/sites/clerk.assembly.ca.gov/files/archive/Statutes/1948/48Vol1_Chapters.pdf
+#
+# In response:
+#
+# Governor Warren received a torrent of objecting mail, and it is not too much
+# to speculate that the objections to Daylight Saving Time were one important
+# factor in the defeat of the Dewey-Warren Presidential ticket in California.
+# -- Ross, p 25
+#
+# On December 8 the governor exercised the option, setting the date to January 1
+# (LA Times 1948-12-09). The transition time was 02:00 (LA Times 1949-01-01).
+#
+# Despite the controversy, in 1949 California voters approved Proposition 12,
+# which established DST from April's last Sunday at 01:00 until September's
+# last Sunday at 02:00. This was amended by 1962's Proposition 6, which changed
+# the fall-back date to October's last Sunday. See:
