The Form of “GMT” stands for the “Greenwich Mean Time”. It had a major hand over the time setting. Greenwich had been defined at the royal observatory of London to determine a period of solar time. It had been measured for the measurement and calculation of Earth criteria.
On 2 Aug 1880 , this didn’t commence their value at the British parliament. On 18 Nov 1883 , it had been commenced and adopted by the U.S.A. (united states of America). Later on , In 1884 it had been adopted and valued at the International Meridian Conference. Due to this measurement , the introduction of 24 Hour times zones had been induced or appeared.
It had stated their measurement with the ‘Zero degree’ line of longitude from the meridian (Earth). This line had been passed from the North pole to the South pole , which had been managed from the old royal observatory situated London.
Greenwich Time had been known as the ‘Global Time Standard’. It was introduced in the year 1884. This had been used as a standard scale to determine the time period. This research had resulted in the benchmark to determine or set the time period or zone.
It had also been known as “International Times”. It was referred to as a base to calculate the time period. It doesn’t regard for an ideal or rough enhancement , it has been managed with absolute reference. It doesn’t change or update with the change of season .
This had defined the greenwich according to direction that , if the location had been defined for the East direction then Greenwich meridian would be ahead with the local time…If it would be in west that it prefers the time behind it.
The Longitude and latitude had been defined for the measurement would be of longitude would be 0 (degree) 0 ‘ 0” and latitude would be 51 (degree) 28’ 38 “ (at the side of North Equator).
