GMT is a time zone officially used in some
European and African countries. The time can be displayed using both the
24-hour format (0 - 24) or the 12-hour format (1 - 12 A.M./P.M.).
Greenwich Mean Time — On 1 November 1884,
GMT was adopted universally at the International Meridian Conference in
Washington, DC, USA. As a result, the International Date Line was drawn up
and 24 time zones were created.
UTC is not a time zone, but a time standard
that is the basis for civil time and time zones worldwide. This means that
no country or territory officially uses UTC as a local time. In 1960, the
International Radio Consultative Committee formalized the concept of
UTC, and it was put into practice the year after. The name Coordinated
Universal Time was officially adopted in 1967.
UTC was adjusted several times until 1972, when leap seconds were introduced
to keep UTC in line with the Earth's rotation, which is not entirely even, and
less exact than atomic clocks.
Why UTC for Coordinated Universal Time and not CUT? UTC does
not favour any particular language. In addition, the advantage of choosing
UTC is that it is consistent with the abbreviation for Universal Time. Language
neutrality sounds like political correctness to me but the world is happy with
the decision.
