GMT to UTC

Greenwich Mean Time (GMT) is a time zone that is often used as a standard time reference for the world. It is based on the line of longitude that passes through the Royal Observatory in Greenwich, London, UK, which is at 0 degrees longitude.

Coordinated Universal Time (UTC) is a standard time reference used globally, and it is often used as a basis for synchronizing clocks and timekeeping systems. UTC is based on the international atomic time scale and is calculated by taking into account the rotation of the Earth, so it is a highly accurate and reliable standard for timekeeping.
