Universal Time (UT) is a time standard based on Earth's rotation. It is a modern continuation of Greenwich Mean Time (GMT), i.e., the mean solar time on the Prime Meridian at Greenwich. In fact, the expression "Universal Time" is ambiguous (when accuracy of better than a few seconds is required), as there are several versions of it, the most commonly used being Coordinated Universal Time (UTC) and UT1 (see below). All of these versions of UT, except for UTC, are based on Earth's rotation relative to distant celestial objects (stars and quasars), but with a scaling factor and other adjustments to make them closer to solar time. UTC is based on International Atomic Time, with leap seconds added to keep it within 0.9 second of UT1.
Prior to the introduction of standard time, each municipality throughout the civilized world set its official clock, if it had one, according to the local position of the Sun (see solar time). This served adequately until the introduction of rail travel in Britain, which made it possible to travel fast enough over long distances to require continuous re-setting of timepieces as a train progressed in its daily run through several towns. Greenwich Mean Time, where all clocks in Britain were set to the same time, was established to solve this problem. Chronometers or telegraphy was used to synchronize these clocks.
Coordinated Universal Time (French: Temps universel coordonné), abbreviated as UTC, is the primary time standard by which the world regulates clocks and time. It is, within about 1 second, mean solar time at 0° longitude; it does not observe daylight saving time. It is one of several closely related successors to Greenwich Mean Time (GMT). For most purposes, UTC is considered interchangeable with GMT, but GMT is no longer precisely defined by the scientific community.
UTC was officially formalized in 1960 by the International Radio Consultative Committee in Recommendation 374, having been initiated by several national time laboratories. The system was adjusted several times until leap seconds were adopted in 1972 to simplify future adjustments. A number of proposals have been made to replace UTC with a new system that would eliminate leap seconds but no consensus has yet been reached.
The current version of UTC is defined by International Telecommunications Union Recommendation (ITU-R TF.460-6), Standard-frequency and time-signal emissions and is based on International Atomic Time (TAI) with leap seconds added at irregular intervals to compensate for the slowing of Earth's rotation. Leap seconds are inserted as necessary to keep UTC within 0.9 seconds of universal time, UT1. See the "Current number of leap seconds" section for the number of leap seconds inserted to date.

Greenwich Mean Time (GMT) is the mean solar time at the Royal Observatory in Greenwich, London. GMT was formerly used as the international civil time standard, now superseded in that function by Coordinated Universal Time (UTC). Today GMT is considered equivalent to UTC for UK civil purposes (but this is not formalized) and for navigation is considered equivalent to UT1 (the modern form of mean solar time at 0° longitude); these two meanings can differ by up to 0.9 s. Consequently, the term GMT should not be used for precise purposes.
Because of Earth's uneven speed in its elliptical orbit and its axial tilt, noon (12:00:00) GMT is rarely the exact moment the sun crosses the Greenwich meridian and reaches its highest point in the sky there. This event may occur up to 16 minutes before or after noon GMT, a discrepancy calculated by the equation of time. Noon GMT is the annual average (i.e., "mean") moment of this event, which accounts for the word "mean" in "Greenwich Mean Time".
"Time" is the fourth track from the English progressive rock band Pink Floyd's 1973 album The Dark Side of the Moon, and the only song on the album credited to all four members of the band, though the lyrics were written by Roger Waters. It is the final Pink Floyd song credited to all four members and the last to feature Richard Wright on lead vocals until "Wearing the Inside Out" on The Division Bell. This song is about how time can slip by, but many people do not realise it until it is too late. Roger Waters got the idea when he realised he was no longer preparing for anything in life, but was right in the middle of it. He has described this realisation taking place at ages 28 and 29 in various interviews. It is noted for its long introductory passage of clocks chiming and alarms ringing, recorded as a quadrophonic test by Alan Parsons, not specifically for the album.
Time is in the key of F# minor. Each clock at the beginning of the song was recorded separately in an antiques store. This is followed by a two-minute passage dominated by Nick Mason's drum solo, with rototoms and backgrounded by a tick-tock sound created by Roger Waters picking two muted strings on his bass. With David Gilmour singing lead on the verses and with Richard Wright singing lead on the bridges and with female singers and Gilmour providing backup vocals, the song's lyrics deal with Roger Waters' realization that life was not about preparing yourself for what happens next, but about grabbing control of your own destiny.

Time zones are based on the fact that the Earth moves 15 degrees longitude each hour. Since there are 24 hours in a day there are 24 standard time zones. (24 hours x 15º=360º) Time zones are counted from the Prime Meridian (0º longitude). Each time zone is counted at 15 º intervals and extends 7½º either side of a central meridian. For example, Sydney, Australia lies in the 150ºE central meridian, and the time zone includes all locations between 142½ºE and 157½ºE.
