Greenwich Mean Time is known as the mean solar time at the Royal Observatory situated in Greenwich, London.
It is a known fact that When the sun is at highest point above the Prime Meridian then it is 1200 noon at Greenwich.
GMT was firstly taken by the United States (USA) on 18 November 1883.
The daily rotation of the Earth is irregular and constantly slows therefore the constitute a much more stable timebase. On 1 January 1972, GMT was superseded as the international civil time standard by Coordinated Universal Time, maintained by an ensemble of atomic clocks around the world
