+ # 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:
