While railroads did indeed invent "standard time" I don't think the length of a day was determined
at each location........ the speed at which the earth rotates was not subject to local regulation..... just
the indexing of clock time in relation to it.
..... and AFAIK this did not make any local time zone better than another for taking freight car photos.
Joe, the first day of spring is the vernal equinox, when the day and
night are each 12 hours. December 21st is the winter solstice, the
shortest day of the year. This is of course all relevant to steam era
freight cars because it was the railroads that invented "standard time"
<G>. Otherwise time, and therefore length of day, was determined at
So a joyous solstice to all of you out there and especially you
