Coordinated Universal Time. The UTC acronym was a compromise between English & French.
UTC was formerly known as GMT (Greenwich Mean Time), and is called Zulu by the military and for aircraft operations (at least in the US, not sure about elsewhere).

The UTC is acronym for "Coordinated Universal Time".The times of various events, particularly astronomical and weather phenomena, are often given in "Universal Time" (abbreviated UT) which is sometimes referred to, now colloquially, as "Greenwich Mean Time" (abbreviated GMT). The two terms are often used loosely to refer to time kept on the Greenwich meridian (longitude zero) 'so then you may ask' :Why is UTC used as the acronym for Coordinated Universal Time instead of CUT?
In 1970 the Coordinated Universal Time system was devised by an international advisory group of technical experts within the International Telecommunication Union (ITU). The ITU felt it was best to designate a single abbreviation for use in all languages in order to minimize confusion. Since unanimous agreement could not be achieved on using either the English word order, CUT, or the French word order, TUC, the acronym UTC was chosen as a compromise.

Coordinated Universal Time (UTC) is the international time standard. It is the current term for what was commonly referred to as Greenwich Meridian Time (GMT). Zero (0) hours UTC is midnight in Greenwich England, which lies on the zero longitudinal meridian. Universal time is based on a 24 hour clock, therefore, afternoon hours such as 4 pm UTC are expressed as 16:00 UTC (sixteen hours, zero minutes)

Coordinated Universal Time (UTC) is a high-precision atomic time standard which approximately tracks Universal Time (UT). It is the basis for legal civil time all over the Earth: time zones around the world are expressed as positive and negative offsets from UTC. In this role it is also referred to as Zulu time (Z), or using the term "Greenwich Mean Time" (GMT).
