At different times in the past, it has been calculated in different ways, including being calculated from noon ; [1] as a consequence, it cannot be used to specify a particular time unless a context is given. Because of Earth's uneven angular velocity in its elliptical orbit and its axial tilt , noon GMT is rarely the exact moment the Sun crosses the Greenwich Meridian [b] and reaches its highest point in the sky there. This event may occur up to 16 minutes before or after noon GMT, a discrepancy described by the equation of time. Noon GMT is the annual average the arithmetic mean moment of this event, which accounts for the word "mean" in "Greenwich Mean Time". Originally, astronomers considered a GMT day to start at noon, [d] while for almost everyone else it started at midnight. To avoid confusion, the name Universal Time was introduced in to denote GMT as counted from midnight. The term GMT should thus not be used for purposes that require precision. As the United Kingdom developed into an advanced maritime nation , British mariners kept at least one chronometer on GMT to calculate their longitude from the Greenwich meridian, which was considered to have longitude zero degrees, by a convention adopted in the International Meridian Conference of Synchronisation of the chronometer on GMT did not affect shipboard time, which was still solar time. But this practice, combined with mariners from other nations drawing from Nevil Maskelyne 's method of lunar distances based on observations at Greenwich, led to GMT being used worldwide as a standard time independent of location. Greenwich Mean Time was adopted across the island of Great Britain by the Railway Clearing House in and by almost all railway companies by the following year, from which the term railway time is derived. It was gradually adopted for other purposes, but a legal case in held " local mean time " to be the official time.

Galactic year Nuclear timescale Precession Sidereal time. DST never observed.

But what is GMT and why is it so important? Solar time varies throughout the year, as the time interval between the Sun crossing a set meridian line changes. But each day measured by a clock has the same length, equal to the average mean length of a solar day. Find out about the Prime Meridian. From until , GMT was the international standard of civil time. Greenwich Mean Time is also the name of the time zone used by some countries in Africa and Western Europe, including in Iceland all year round.

It is based on the Royal Observatory in Greenwich, located in London, United Kingdom , and is considered a global reference for measuring time. Established in , GMT is used as the standard time to define time zones in relation to solar time. To check the current time in GMT, it is necessary to know which time zone you are in and convert it in relation to the Greenwich time zone. This can be a bit confusing, especially for those who need to communicate or do business with people from other countries. To avoid possible confusions, it is important to pay attention to the details and always use reliable references to convert the times.

Areas of extreme latitude are more likely to use DST. It was the first clock ever to show Greenwich Mean Time directly to the public. The switch to daylight saving time does not affect UTC. Originally, astronomers considered a GMT day to start at noon, [d] while for almost everyone else it started at midnight. Kankan Kankan. Retrieved February 12, Legally, the civil time used in the UK is called "Greenwich mean time" without capitalisation , with an exception made for those periods when the Summer Time Act orders an hour's shift for daylight saving. In Google Calendar , calendar events are stored in UTC although shown in local time and might be changed by a time-zone changes, [46] although normal daylight saving start and end are compensated for similar to much other calendar software.

However, in practice each ship may choose what time to observe at each location. Soon after, he was appointed as the first Astronomer Royal and moved into the new Royal Observatory in Greenwich. Liverpool England. Although that instrument still survives in working order, it is no longer in use and now the meridian of origin of the world's longitude and time is not strictly defined in material form but from a statistical solution resulting from observations of all time-determination stations which the BIPM takes into account when co-ordinating the world's time signals.
