Gmt vs utc time11/11/2022 ![]() In common use, when fractions of a second are considered not very important, GMT can be taken equivalent to UTC. The difference between Greenwich Mean Time and Coordinated Universal Time is measured in fractions of a second. ![]() Thus, it can be said that the UTC is Internet based time standard. UTC is used by the Network Time Protocol, created to synchronize the clocks of many computers over the Internet. It is also the basis of the satellite global positioning system ( GPS). UTC is the time standard used for Internet and World Wide Web standards. It is interesting to note that leap seconds are added to UTC to compensate for the slowing rotation of the Earth. It is important to know that leap seconds are used to allow UTC to track the mean solar time in the Royal Observatory in Greenwich, London. To determine the international standard of Coordinated Universal Time, the Bureau of Weights and Measures (BIPM) in Paris Coordinates data from atomic clocks located in timing laboratories around the globe. It is a method of measuring time using atomic clocks. UTC, which stands for Coordinated Universal Time, is an international time scale recommended by the International Bureau of Weights and Measures (BIPM) as the legal basis for time. They are the United Kingdom, Belgium, Republic of Ireland, and Canada. As a matter of fact, several countries adopt GMT in their legislation. It is used primarily by bodies associated with the United Kingdom like the BBC World Service, the Royal Navy, and the Met Office. GMT, which stands for Greenwich Mean Time, is based on astronomical observations. UTC is based on International Atomic Time (TAI). GMT refers to the time maintained at the Royal Observatory in Greenwich, London called the mean solar time. GMT is Greenwich Mean Time whereas UTC is Coordinated Universal Time. Before going into those differences, let us first see what GMT and UTC stand for. However, there are some other differences between GMT and UTC when it comes to usage. ![]() When it comes to time keeping, one should know that the time difference between GMT and UTC is a fraction of a second and, for most common purposes, that difference is insignificant and considered as no difference. ![]()
