UT(C), etc.

Coordinated Universal Time (abbreviated UTC)[1] is the primary time standard by which the world regulates clocks and time. Computer servers, online services and other entities that rely on having a universally accepted time use UTC for that purpose.
Coordinated Universal Time is a time standard based on International Atomic Time (TAI) with leap seconds added at irregular intervals to synchronize with the Earth's rotation.[2]
UTC is conceptually different from Universal Time and Greenwich Mean Time (GMT), but it can be used interchangeably where sub-second precision is not required.
It may also be viewed as a compromise between TAI and a precise variant of Universal Time, UT1, because each second is as precisely the same length as atomic can determine (as with TAI), but remains within a second of UT1
