801 # From Paul Eggert (2018-11-30):
802 # A brief but entertaining history of time in Indiana describes a 1949 debate
803 # in the Indiana House where city legislators (who favored "fast time")
804 # tussled with farm legislators (who didn't) over a bill to outlaw DST:
805 # "Lacking enough votes, the city faction tries to filibuster until time runs
806 # out on the session at midnight, but rural champion Rep. Herbert Copeland,
807 # R-Madison, leans over the gallery railing and forces the official clock
808 # back to 9 p.m., breaking it in the process. The clock sticks on 9 as the
809 # debate rages on into the night. The filibuster finally dies out and the
810 # bill passes, while outside the chamber, clocks read 3:30 a.m. In the end,
811 # it doesn't matter which side won. The law has no enforcement powers and
812 # is simply ignored by fast-time communities."
