History

Liberia first adopted the UTC offset -0:43:08 (called Liberia Mean Time; LMT) as it was the geographical central meridian on which the capital Monrovia was located. [5] The time zone was renamed to Monrovia Mean Time in 1882. [5] In March 1919, the offset was redefined forward by 1 minute and 22 seconds to -0:44:30. [6] [7] Liberia adopted Greenwich Mean Time (GMT; UTC±00:00) on 7 January 1972. [8]

Greenwich Mean Time Time zone of western Europe, same as WET

Greenwich Mean Time (GMT) is the mean solar time at the Royal Observatory in Greenwich, London, counted from midnight. At different times in the past, it has been calculated in different ways, including being calculated from noon; as a consequence, it cannot be used to specify a particular time unless a context is given. The term 'GMT' is also used as one of the names for the time zone UTC+00:00 and, in UK law, is the basis for civil time in the United Kingdom.

Time zone Area that observes a uniform standard time

A time zone is an area that observes a uniform standard time for legal, commercial and social purposes. Time zones tend to follow the boundaries between countries and their subdivisions instead of strictly following longitude, because it is convenient for areas in frequent communication to keep the same time.

In modern usage, civil time refers to statutory time scales designated by civilian authorities, or to local time indicated by clocks. Modern civil time is generally standard time in a time zone at a fixed offset from Coordinated Universal Time (UTC) or from Greenwich Mean Time (GMT), possibly adjusted by daylight saving time during part of the year. UTC is calculated by reference to atomic clocks, and was adopted in 1972. Older systems use telescope observations.

Time in the Czech Republic

Time in the Czech Republic is given by Central European Time and Central European Summer Time. Daylight saving time is observed from the last Sunday in March to the last Sunday in October. The Czech Republic has observed Central European Time since 1979. Until 1993 when Czechoslovakia was separated into the Czech Republic and Slovakia, they also had Central European Time and Central European Summer Time. After the summer months, time in the Czech Republic is shifted back by one hour to Central European Time. Like most states in Europe, Summer time is observed in the Czech Republic, when time is shifted forward by one hour, two hours ahead of Greenwich Mean Time.
