Greenwich Mean Time (GMT) is the local mean time at the Royal Observatory in Greenwich, London, counted from midnight.

This is a list representing time zones by country. Countries are ranked by total number of time zones on their territory. Time zones of a country include that of dependent territories (except Antarctic claims). France, including its overseas territories, has the most time zones with 12 (13 including its claim in Antarctica and all other counties ).
Such designations can be ambiguous; for example, "CST" can mean China Standard Time (UTC+08:00), Cuba Standard Time (UTC−05:00), and (North American) Central Standard Time (UTC−06:00), and it is also a widely used variant of ACST (Australian Central Standard Time, UTC+9:30). Such designations predate both ISO 8601 and the internet era; in ...
Daylight saving time was introduced by the Summer Time Act 1916 (6 & 7 Geo. 5. c. 14), which was implemented in 1916 as GMT plus one hour and Dublin Mean Time plus one hour.

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.
Western European Time (WET, UTC+00:00) is a time zone covering parts of western Europe and consists of countries using UTC+00:00 (also known as Greenwich Mean Time, abbreviated GMT). [ 1 ] [ 2 ] It is one of the three standard time zones in the European Union along with Central European Time and Eastern European Time .
The military time zones are a standardized, uniform set of time zones for expressing time across different regions of the world, named after the NATO phonetic alphabet. The Zulu time zone (Z) is equivalent to Coordinated Universal Time (UTC) and is often referred to as the military time zone.
Thus the local mean time in most of Ireland is closer to UTC-01:00 time than to GMT. The Standard Time Act 1968 legally established that "the time for general purposes in the State (to be known as standard time) shall be one hour in advance of Greenwich mean time throughout the year". [2] This act was amended by the Standard Time (Amendment ...
