Until the advent of the railways, the United Kingdom used local mean time. Greenwich Mean Time was adopted first by the Great Western Railway in and a few others followed suit in the following years. In it was adopted by the Railway Clearing House , and by almost all railway companies by the following year. It was from this initiative that the term " railway time " was derived. It was gradually adopted for other purposes, but the legal case of Curtis v March in held " local mean time " to be the official time. To bring this about, the clocks were not put back by an hour at the end of summer in BST having started early, on 25 February From to , the day following the third Saturday in March was the start of British Summer Time unless that day was Easter Sunday, in which case BST began a week earlier , with the day following the fourth Saturday in October being the end of British Summer Time. From to , the dates were set in line with various European Directives. Since the start and end date are the same in both the United Kingdom and the European Union. Authority over the time zone in Northern Ireland can be legislated by the Northern Ireland Assembly [20] but the power has never been used, as the Republic has followed the UK. In Scotland and Wales, time zone is a reserved matter , meaning that only the Parliament of the United Kingdom has power to legislate. There are several entries for UK possessions around the world.

But what is GMT and why is it so important? Solar time varies throughout the year, as the time interval between the Sun crossing a set meridian line changes. But each day measured by a clock has the same length, equal to the average mean length of a solar day. Find out about the Prime Meridian. From until , GMT was the international standard of civil time. Greenwich Mean Time is also the name of the time zone used by some countries in Africa and Western Europe, including in Iceland all year round. John Flamsteed came up with the formula for converting solar time to mean time, and published a set of conversion tables in the early s. Soon after, he was appointed as the first Astronomer Royal and moved into the new Royal Observatory in Greenwich.

Noon GMT is the annual average the arithmetic mean moment of this event, which accounts for the word "mean" in "Greenwich Mean Time". Originally, astronomers considered a GMT day to start at noon, [d] while for almost everyone else it started at midnight. To avoid confusion, the name Universal Time was introduced in to denote GMT as counted from midnight. The term GMT should thus not be used for purposes that require precision. As the United Kingdom developed into an advanced maritime nation , British mariners kept at least one chronometer on GMT to calculate their longitude from the Greenwich meridian, which was considered to have longitude zero degrees, by a convention adopted in the International Meridian Conference of
