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.
On April 18, 2021 some of the lighter areas are on UTC+1 (British Summer Time, Irish Standard Time, WEST).

It is now often used to refer to Coordinated Universal Time (UTC) when this is viewed as a time zone, and in casual use the two are the same. In the military, GMT is known as Zulu time. Greenwich Mean Time was the same as Universal Time (UT), a standard astronomical concept used in many technical fields, until the introduction of UTC in 1972.
On April 18, 2021 the lighter areas are on UTC+1 (British Summer Time, Irish Standard Time).
