Re: I Should've Been Asleep Two Hours Ago...

Before the railroad spread out in France, every place
had its own local time (not its local date, though...)

By the way, when thinking about calendars, let's not
forget that the length of the day slowly changes too.
In fact, every changes: the time for the Earth to
rotate on its own axis, the time for the Moon to
orbitate around the Earth, the time for the Earth to
orbitate around the Sun, the distance between Moon and
Earth, Earth and Sun, etc. So what steady unit could
we use ?
