Offset: UTC is the same as Greenwich Mean Time (GMT).
Coordinated Universal Time (UTC) is the world time standard that regulates clocks and time. It is the successor to Greenwich Mean Time (GMT). For casual use, UTC is the same as GMT, but UTC is the standard the scientific community uses.
UTC has been the time standard commonly used across the world since 1972. It is used in many technical fields, such as aviation and meteorology, and to synchronize time across internet networks.
Today some of the lighter areas are on UTC+1 (British Summer Time, Irish Standard Time, WEST).
