UTC represents the Coordinated Universal Time, formerly referred to as Greenwich Mean Time, or GMT.

Formally, the value for a local time with respect to UTC is defined as follows:

UTC = local time - time_zone_displacement

where the value for time_zone_displacement is the time that must be subtracted from local time to produce the value for UTC, which is arbitrarily defined as zero hours displacement from the Greenwich meridian.
