Nevertheless, both of these time standards are widely used in the world for a similar purpose of time coordination. The implementation of Greenwich Mean Time (GMT) was the first step to determine the time zone of other countries in regard to GMT+0. Therefore, the difference in time for other countries is indicated either by adding or subtracting hours from GMT time. The primary difference remains to be the fact that GMT is the denomination of a timezone, while UTC is the title of the time standard. The use of GMT began in 19th century Great Britain when British mariners would use the time at the Greenwich Meridian and the time at their ship’s position to determine the ship’s longitude.<\/p>\n<\/p>\n
Time zones today are a certain number of hours or hours and minutes behind or ahead of UTC. When European Summer Time is not in effect, UTC matches the time zone of the United Kingdom. By the mid-nineteenth century, Greenwich Mean Time (GMT) had been established as the primary reference time zone for the British Empire and for much of the world.<\/p>\n<\/p>\n
We have always looked to the stars for answers to these questions. The solstices and equinoxes provided points of reference for us to use in our pursuit. For over 1,300 years the sun\u2019s position in a local area was the basis for the time of day. The sun was always due east at 6 AM, above your head at noon, and in the west at 6 PM.<\/p>\n<\/p>\n

Other than this, one of the biggest differences between GMT and UTC is that UTC does not observe Daylight Saving Time. From 1850 to 1893, the Shepherd master clock led the time system of Great Britain. Using the telegraph wires, the clock sent the time to the major cities such as London, Edinburgh, Glasgow, Dublin, Belfast, and more. Even more, from 1866 time was also sent to Harvard University in Cambridge and Massachusetts. The Shepherd gate clock is considered as the first GMT watch ever that showed the public Greenwich Mean Time.<\/p>\n<\/p>\n
During summer, the UK is in the BST (British Standard Time) time zone. \u201cIndeed, even the Greenwich meridian itself is not quite what it used to be\u2014defined by \u00ab\u00a0the center of the transit instrument at the Observatory at Greenwich\u00a0\u00bb. In 1880 GMT was adopted as the main time standard for all of Great Britain\u2019s purposes. The Isle of Man adopted the standard in 1883, Jersey followed in 1898, and Guernsey in 1913.
