Acronym: niversal ime oordinate Weather: one of several names for the twenty-four hour time which is used throughout the scientific and military communities. Other names for this time system are Zulu (Z) and Greenwich Mean Time (GMT)
Co-ordinated universal time; previously: Greenwich Mean Time, Zulu
(n.) Universal Coordinate Time (accepted acronym from the French).
Universal Time Code. edit edit
This is the official world wide reference used for time measurement. UTC used to be known as Greenwich Mean Time (GMT).
niversal ime oordinated, previously known as Greenwich Mean Time (GMT; 1928 - 1972). UTC was introduced in 1972 and replaces midnight GMT with 0000h (0 hours).
The times of various events, particularly astronomical and weather phenomena, are often given in "Universal Time" (abbreviated UTC) which is sometimes referred to, now colloquially, as "Greenwich Mean Time" (abbreviated GMT). The two terms are often used loosely to refer to time kept on the Greenwich meridian (longitude zero), five hours ahead of Eastern Standard Time. Times given in UT are almost always given in terms of a 24-hour clock. Thus, 14:42 (often written simply 1442) is 2:42 p.m., and 21:17 (2117) is 9:17 p.m. Sometimes a Z is appended to a time to indicate UT, as in 0935Z.

Universal Time Coordinator. A universal time standard, referencing the time at Greenwich, England. Also referred to as GMT or Zulu time.
A time scale based on the rotation of the earth that is disseminated by most broadcast time services.
Abbreviation for niversal ime oordinated and formerly known as reenwich ean ime ( GMT).
UNIVERSAL TIME COORDINATED - SAME AS GREENWICH MEAN TIME (GMT).
oordinated niversal ime is a time scale that couples Greenwich Mean Time, which is based solely on the Earth’s inconsistent rotation rate, with highly accurate atomic time. When atomic time and Earth time approach a one second difference, a leap second is calculated into UTC. UTC was devised on January 1st, 1972 and is coordinated inParis by the International Bureau of Weights and Measures (BIPM). For most practical purposes associated with the Radio Regulations, UTC is equivalent to mean solar time at the prime meridian (0 longitude), formerly expressed in GreenwichMean Time (GMT). The maintenance by BIPM includes cooperation among various national laboratories around the world. The full definition of UTC is contained in CCIR Recommendation 460-4. The GPS system time is different from the UTC time by a whole number of leap seconds (13 at the time of this writting).
Coordinated Universal Time, or local time at the 0° Greenwich meridian. Also called Zulu (Z) time.
UTC (Coordinated Universal Time) is the name of the international time standard and is identical to ...
abbreviation for co-ordinated universal time. Also known as GMT (Greenwich Mean Time). This is the time at the international date line. The time zones are all based on UTC or GMT + or - however many hours.
Universal Time Coordinate (eo) or Universal Time Corrected (ENVISAT)
Coordinated Universal Time ‹¦'袊E
Universal time coordinated. An international, highly accurate and stable uniform atomic time system kept very close, by offsets, to the universal time corrected for seasonal variations in the earth's rotation rate. Maintained by the U.S. Naval Observatory. GPS time is directly relatable to UTC: UTC-GPS = seconds. (The changing constant = 5 seconds in 1988.)
coordinated universal time; same as GMT
Coordinated Universal Time. Time zone at zero degrees longitude. Formerly called Greenwich Mean Time (GMT) and Zulu time.
See Coordinated Universal Time.
The standard time common to every place in the world. Formerly and still widely called Greenwich Mean Time (GMT) and also World Time, UTC nominally reflects the mean solar time along the Earth's prime meridian. UTC is indicated by a z at the end of the value, for example, 200011281010z.
Coordinated Universal Time. A time-scale which forms the basis of a coordinated dissemination of standard frequencies and time signals throughout the world.
Coordinated Universal Time (abbreviated as UTC, and therefore often spelled out as Universal Time Coordinated and sometimes as Universal Coordinated Time) is the standard time common to every place in the world. Formerly and still widely called Greenwich Mean Time (GMT) and also World Time, UTC nominally reflects the mean solar time along the Earth's prime meridian.
An international time standard similar to Greenwich mean time. UTC stands for "coordinated universal time." When scheduling policies to run at a specific time, you can enter the time in UTC or local time.

Coordinated Universal Time All times are EDT (Coordinated Universal Time [UTC] minus four hours) unless otherwise stated. Tracks are classified from Class 1, with speed restricted to a maximum of 10 mph for freight trains, to Class 6 with a maximum speed of 110 mph for freight trains. Most heavily used main tracks are Class 4 with a maximum designated speed of 60 mph for freight trains.

Universal Time Coordinated- after the French equivalent.
In 1970 the Coordinated Universal Time system was devised by an international advisory group of technical experts within the International Telecommunication Union (ITU). The ITU felt it was best to designate a single abbreviation for use in all languages in order to minimize confusion. Since unanimous agreement could not be achieved on using either the English word order, CUT, or the French word order, TUC, the acronym UTC was chosen as a compromise.
Universal Time Coordinated; uniform atomic time system kept very closely to UT2 by offsets. Maintained by the U.S. Naval Observatory. GPS time is directly relatable to UTC. UTC-GPS = 9 seconds (in 1994)
Universal Time Coordinated: The time on which all G.P.S. signals are synchronized.. The same as Greenwich Mean Time.
Coordinated Universal Time. All satellite times are reported in UTC rather than in local time or daylight-saving (summer) time. See also GMT.
Coordinated Universal Time, also known as Greenwich Mean Time (GMT), Greenwich Mean Time is based upon the time at the zero degree meridian that crossed through Greenwich, England and is used as a world time and date standard.
Universal Time Co-ordinated. The UTC offset is the same as the GMT offset.
Universal Time Coordinated. A global standard for time. Synonyms: Greenwich Mean Time (GMT); zulu time.

Universal Coordinated Time. This is the replacement for GMT. It defines a reference time base that is internationally recognized and supported.

(Universal Time Coordinated, formerly known as Greenwich Mean Time or GMT) All ATC services worldwide refer to UTC to indicate flight times. Local time is measured and stated in terms of UTC: Swiss Winter Time is one hour ahead of UTC (UTC + 1), while Swiss Summer Time is UTC + 2, or two hours ahead.
Coordinated Universal Time. The time scale based on the atomic second but corrected every now and again to keep it in approximate sync with the earth's rotation. The corrections show up as the leap seconds put into UTC - usually on New Year's Eve. In the most common usage, the terms GMT and UTC are identical.
A term which, for practical purposes, has the same meaning as Greenwich Mean Time (GMT).
Universal Time Coordinated. A universal time based on the Greenwich Meridian used by the military and in aviation. Greenwich Mean Time (GMT) can be considered approximately equivalent to Universal Time Coordinated (UTC). GMT as such is now obsolete however, being replaced by UTC. Using this timezone/standard avoids errors and problems associated with different time zones and summer times operational in different countries.
UNIVERSAL TIME COORDINATE. One of several names for the twenty-four hour time that is used throughout the scientific and military communities. Other names for this time measurement are Greenwich Mean Time (GMT) or Zulu Time (Z). See Greenwich Mean Time for more information.
The mean solar time at the Royal Greenwich Observatory in Greenwich near London, England. On January 1, 1972, GMT was replaced as the international time reference by Coordinated Universal Time (UTC), maintained by an ensemble of atomic clocks around the world.
