It is the difference between UT1 and UTC (Universal Coordinated Time) that is kept below 0.9s by the application of leap seconds. GMT has been referred to as “UT1", which directly corresponds to the rotation of the Earth, and is subject to that rotation’s slight irregularities. Although that instrument still survives in working order, it is no longer in use and now the meridian of origin of the world's longitude and time is not strictly defined in material form but from a statistical solution resulting from observations of all time-determination stations which the Historically, GMT has been used with two different conventions for numbering hours. The long-standing astronomical convention, dating from the work of Legally, the civil time used in the UK is called "Greenwich mean time" (without capitalisation), according to the During the experiment of 1968 to 1971, when the British Isles did not revert to Greenwich Mean Time during the winter, the all-year BBC radio stations broadcast the "six pips" of the Several countries define their local time by reference to Greenwich Mean Time.Greenwich Mean Time is used as standard time in the following countries and areas, which also advance their clocks one hour (GMT+1) in summer.

Greenwich Mean Time or GMT is clock time at the Royal Observatory in Greenwich, London. Since legal, political, social and economic criteria, in addition to physical or geographical criteria, are used in the drawing of time zones, actual time zones do not precisely adhere to meridian lines. As Greenwich, due to the presence of the Royal Observatory, was the national centre for time and had been since 1675, the choice was obvious. See more. Christopher Wren was commissioned to design the domed building. Where east meets west. When the sun is at its highest point exactly above the Prime Meridian, it is 1200 noon at Greenwich.

Greenwich Mean Time or GMT is clock time at the Royal Observatory in Greenwich, London. John Flamsteed was appointed the Astronomer Royal. GMT was then adopted by the United States (USA) on 18 November 1883.

Today, GMT is used as the UK’s civil time. Europe africa north america antarctica.

When the sun is at its highest point exactly above the GMT is also a time zone, used by the United Kingdom of Great Britain and Northern Ireland Every 15° longitude represents one hour's difference in time: (24 x 15 = 360, the degrees of a circle). Prior to that there were over 300 local times in the USA. On 1 November 1884, GMT was adopted universally at the International Meridian Conference in Washington, DC, USA. This time zone is in use during standard time in: Europe, Africa, North America, Antarctica. GMT was originally set up to aid naval navigation when travel around the globe started to open up with the discovery of the “New World” (America) in the fifteenth century. To avoid confusion, the name The term "GMT" is especially used by bodies connected with the Greenwich Mean Time was adopted across the island of Indeed, even the Greenwich meridian itself is not quite what it used to be—defined by "the centre of the transit instrument at the Observatory at Greenwich".

Inextricably linked with Greenwich Mean Time, it also sits at the centre of our system of time zones.
