UTC
UTC is the acronym for Coordinated Universal Time.
Coordinated Universal Time
The standard time reference for many applications and systems, including navigation, communication, and financial systems, as well as for civil timekeeping and legal purposes. UTC is based on International Atomic Time (TAI), which measures the average time elapsed between two specific points in the orbits of Earth’s moon.
UTC provides a uniform time scale that is used by many systems, including the GPS, the Internet, and many other technologies that require accurate and consistent timekeeping. UTC is kept within 0.9 seconds of the TAI time scale, and the use of atomic clocks and other timekeeping technologies maintains its accuracy.
UTC was first implemented in 1972 as a successor to TAI and GMT. It was designed to be a more precise and uniform standard for international timekeeping, as TAI and GMT were both subject to slight variations due to the Earth’s irregular rotation.
