432 # From Paul Eggert (2015-04-06): |
|
433 # In 1950s Nashville a public clock had dueling faces, one for conservatives |
|
434 # and the other for liberals; the two sides didn't agree about the time of day. |
|
435 # I haven't found a photo of this clock, nor have I tracked down the TIME |
|
436 # magazine report cited below, but here's the story as told by the late |
|
437 # American journalist John Seigenthaler, who was there: |
|
438 # |
|
439 # "The two [newspaper] owners held strongly contrasting political and |
|
440 # ideological views. Evans was a New South liberal, Stahlman an Old South |
|
441 # conservative, and their two papers frequently clashed editorially, often on |
|
442 # the same day.... In the 1950s as the state legislature was grappling with |
|
443 # the question of whether to approve daylight saving time for the entire state, |
|
444 # TIME magazine reported: |
|
445 # |
|
446 # "'The Nashville Banner and The Nashville Tennessean rarely agree on anything |
|
447 # but the time of day - and last week they couldn't agree on that.' |
|
448 # |
|
449 # "It was all too true. The clock on the front of the building had two faces - |
|
450 # The Tennessean side of the building facing west, the other, east. When it |
|
451 # was high noon Banner time, it was 11 a.m. Tennessean time." |
|

|
453 # Seigenthaler J. For 100 years, Tennessean had it covered. |

881 # From Paul Eggert (2018-11-30): |
|
882 # A brief but entertaining history of time in Indiana describes a 1949 debate |
|
883 # in the Indiana House where city legislators (who favored "fast time") |
|
884 # tussled with farm legislators (who didn't) over a bill to outlaw DST: |
|
885 # "Lacking enough votes, the city faction tries to filibuster until time runs |
|
886 # out on the session at midnight, but rural champion Rep. Herbert Copeland, |
|
887 # R-Madison, leans over the gallery railing and forces the official clock |
|
888 # back to 9 p.m., breaking it in the process. The clock sticks on 9 as the |
|
889 # debate rages on into the night. The filibuster finally dies out and the |
|
890 # bill passes, while outside the chamber, clocks read 3:30 a.m. In the end, |
|
891 # it doesn't matter which side won. The law has no enforcement powers and |
|
892 # is simply ignored by fast-time communities." |
|
893 # How Indiana went from 'God's time' to split zones and daylight-saving. |

1100 # Although Shanks says Detroit observed DST in 1967 from 06-14 00:01 |
1197 # Due to a complicated set of legal maneuvers, in 1967 Michigan did |
1101 # until 10-29 00:01, I now see multiple reports that this is incorrect. |
1198 # not start daylight saving time when the rest of the US did. |
1102 # For example, according to a 50-year anniversary report about the 1967 |
1199 # Instead, it began DST on Jun 14 at 00:01. This was big news: |
