Greenwich Mean Time GMT is a term originally referring gmt to utc difference 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. The ITU felt it was best to designate a single abbreviation for use in all languages in order to minimize confusion.

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 advancement of telecommunication technologies influenced the creation of an even more precise system of time identification. In particular, the concept of Coordinated Universal Time UTC was designed to provide a more accurate timekeeping system. Nevertheless, both of these time standards are widely used in the world for a similar purpose of time coordination.
