The official abbreviation for Coordinated Universal Time is UTC. This abbreviation arose from a desire by the International Telecommunication Union and the International Astronomical Union to use the same abbreviation in all languages.
Two components are used to determine UTC: 1  International Atomic Time (TAI) : A time scale that combines the output of some 400 highly precise atomic clocks worldwide, and provides the exact speed for our clocks to tick. 2  Universal Time (UT1), also known as astronomical time or solar time, refers to the Earth's rotation.
