This was not always the case: before the introduction of UTC on January 1, , Greenwich Mean Time served as an international reference time and was used as a standard in science, aviation and various other fields. The existence of such a reference time is indispensable: Uniform time information is essential not only in meteorology, but also for Internet-based applications, in space and even in Antarctica. A look at these application areas already suggests that maximum precision is of enormous importance when using a global standard time.

Greenwich Mean Time GMT is a term originally referring to mean solar time at the Royal Observatory, Greenwich where a system was first developed around for tracking time based on the rotation of the Earth.

While GMT was widely used historically, it is now replaced by UTC as the global timekeeping standard across vast regions and countries. Historically, GMT has been widely used as a timekeeping standard especially for navigation and astronomy, mainly during the era of maritime navigation. UTC is the primary time standard by which the world regulates its time and clocks. It is maintained using highly precise atomic clocks and is used for keeping a uniform and standardized time worldwide. To maintain its preciseness, leap seconds are taken into account in UTC.
