what is the uk time zone in utc
Time in the United Kingdom The United Kingdom uses Greenwich Mean Time or Western European Time (UTC) and British Summer Time or Western European Summer Time (UTC+01:00).
Coordinated Universal Time For most common and legal-trade purposes, the fractional second difference between UTC and UT (GMT) is inconsequentially small. Greenwich Mean Time is the legal standard in Britain during the winter, and this notation is familiar to and used by the population.[21]
Time Earth is split up into a number of time zones. Most time zones are exactly one hour apart, and by convention compute their local time as an offset from GMT. For example, time zones at sea are based on GMT. In many locations (but not at sea) these offsets vary twice yearly due to daylight saving time transitions.
Central Time Zone Central Standard Time (CST) is six hours behind Coordinated Universal Time (UTC). During summer most (but not all) of the zone uses daylight saving time (DST), and changes to Central Daylight Time (CDT) which is five hours behind UTC.

Coordinated Universal Time The time zone using UTC is sometimes denoted UTC±00:00 or by the letter Z—a reference to the equivalent nautical time zone (GMT), which has been denoted by a Z since about 1950. Time zones were identified by successive letters of the alphabet and the Greenwich time zone was marked by a Z as it was the point of origin. The letter also refers to the "zone description" of zero hours, which has been used since 1920 (see time zone history). Since the NATO phonetic alphabet word for Z is "Zulu", UTC is sometimes known as "Zulu time". This is especially true in aviation, where "Zulu" is the universal standard.[24] This ensures all pilots regardless of location are using the same 24-hour clock, thus avoiding confusion when flying between time zones.[25] See the list of military time zones for letters used in addition to Z in qualifying time zones other than Greenwich.
