Coordinated Universal Time (UTC) is a high-precision atomic time standard. UTC has uniform seconds defined by International Atomic Time (TAI), with leap seconds announced at irregular intervals to compensate for the Earth's slowing rotation and other discrepancies. Leap seconds allow UTC to closely track Universal Time (UT), a time standard based not on the uniform passage of seconds, but on the Earth's angular rotation.
Time zones around the world are expressed as positive or negative offsets from UTC. Local time is UTC plus the time zone offset for that location, plus an offset (typically +1) for daylight saving time, if in effect.
As the zero-point reference, UTC is also referred to as Zulu time (Z). See Time zones below.

|English||CUT (coordinated universal time)|
|French||TUC (temps universel coordonné)|
The International Telecommunication Union wanted Coordinated Universal Time to have a single abbreviation for all languages. English speakers and French speakers each wanted the initials of their respective languages' terms to be used internationally: "CUT" for "coordinated universal time" and "TUC" for "temps universel coordonné". This resulted in the final compromise of using UTC.
"UTC" also has the benefit that it fits in with the pattern for the abbreviations of variants of Universal Time. "UT0", "UT1", "UT1R", and others exist, so appending "C" for "coordinated" to the base "UT" is very satisfactory for those who are familiar with the other types of UT.
"UTC" has been erroneously expanded into "Universal Time Code", "Universal Time Convention", or "Universal Time Coordinated."
