Coordinated Universal Time
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).

Kosrae Time
Offset: KOST is 11 hours ahead of Greenwich Mean Time (GMT).
Countries using this time zone: Micronesia
Principal Cities: The largest city in the KOST time zone is Tofol in Micronesia, with about 9,686 people. Other major cities in this time zone include Lelu.
Daylight Saving: Clocks in Kosrae Time (KOST) do not change for daylight saving time, so KOST stays the same throughout the year. Other time zones may set clocks forward in summer and back in winter; see upcoming clock changes worldwide.
