His 1870 proposal was based on Washington, DC,   # but in 1872-05 he moved the proposed origin to Greenwich. - # His proposal was adopted by the railroads on 1883-11-18 at 12:00, - # and the most of the country soon followed suit. +     -  + # From Paul Eggert (2018-03-20): + # Dowd's proposal left many details unresolved, such as where to draw + # lines between time zones. The key individual who made time zones + # work in the US was William Frederick Allen - railway engineer, + # managing editor of the Travelers' Guide, and secretary of the + # General Time Convention, a railway standardization group. Allen + # spent months in dialogs with scientific and railway leaders, + # developed a workable plan to institute time zones, and presented it + # to the General Time Convention on 1883-04-11, saying that his plan + # meant "local time would be practically abolished" - a plus for + # railway scheduling. By the next convention on 1883-10-11 nearly all + # railroads had agreed and it took effect on 1883-11-18. That Sunday + # was called the "day of two noons", as some locations observed noon + # twice. Allen witnessed the transition in New York City, writing: + # + # I heard the bells of St. Paul's strike on the old time. Four + # minutes later, obedient to the electrical signal from the Naval + # Observatory ... the time-ball made its rapid descent, the chimes + # of old Trinity rang twelve measured strokes, and local time was + # abandoned, probably forever. + # + # Most of the US soon followed suit.
