History of Time Zones in the UK

The United Kingdom was one of the 1st countries to use a standard time for the whole country, instead of each place keeping its own local mean time.

The UK's capital, London, changed from London Time to Greenwich Mean Time in 1847.

GMT, or Railway Time, as it was known then, was first used by the UK's railway companies. Until 1972, GMT set the standard for standard for civil time worldwide. It referred to solar time at the prime meridian, which runs near the Royal Observatory in Greenwich. Today's world time standard, Coordinated Universal Time (UTC), is still located on the prime meridian (0°longitude).
