From Grandin's Fordlandia, p. 224.
[Ford] was twenty-two when, in 1885, most of Detroit refused to obey a municipal ordinance to promote "the unification of time," as the campaign to get the United States to accept the Greenwich meridian as the universal standard was called. "Considerable confusion" prevailed, according to the Chicago Daily Tribune, as Detroit "showed her usual conservatism in refusing to adopt Standard Time." It took more than two decades to get the city to fully "abandon solar time" and set its clocks back twenty-eight minutes and fifty-one seconds to harmonize with Chicago and the rest of the Midwest (the city would switch to eastern standard time in 1915, both to have more sunlight hours and to synchronize the city's factories with New York banks).Time is relative! (Yes I mean time of day, not the passing of, but that's relative too.)
