[edit] December 1, 1st time zone in the world by British railways?
Greenwich Mean Time (GMT) was established in 1675 as an aid to determine longitude at sea by mariners. The first time zone in the world was established by British railways on December 1, 1847 - with GMT hand-carried on chronometers. About August 23, 1852, time signals were first transmitted by telegraph from the Royal Greenwich Observatory. Even though 98% of Great Britain's public clocks were using GMT by 1855, it was not made Britain's legal time until August 2, 1880. Some old clocks from this period have two minute hands — one for the local time, one for GMT. This only applied to the island of Great Britain, and not to the island of Ireland. http://en.wikipedia.org/wiki/Time_zone
