It is the basis for Coordinated Universal Time ( UTC ), which is used for civil timekeeping all over the Earth's surface, and for Terrestrial Time, which is used for astronomical calculations.

TAI in this form was synchronised with Universal Time at the beginning of 1958, and the two have drifted apart ever since, due to the changing motion of the Earth.

This was a compromise arrangement for a broadcast time scale: a linear transformation of the BIH's atomic time meant that the time scale was stable and internationally synchronised, while approximating UT1 means that tasks such as navigation which require a source of Universal Time continue to be well served by public time broadcasts.

ΔT, Delta T, delta-T, deltaT, or DT is the time difference obtained by subtracting Universal Time ( UT ) from Terrestrial Time ( TT ): ΔT = TT − UT.

Universal Time is a time scale based on the Earth's rotation, which is somewhat irregular over short periods ( days up to a century ), thus any time based on it cannot have an accuracy better than 1: 10 < small >< sup > 8 </ sup ></ small >.

) Physically, the meridian of Greenwich in Universal Time is almost always to the east of the meridian in Terrestrial Time, both in the past and in the future.

Thus the aim developed, to provide a new time scale for astronomical and scientific purposes, to avoid the unpredictable irregularities of the mean solar time scale, and to replace for these purposes Universal Time ( UT ) and any other time scale based on the rotation of the Earth around its axis, such as sidereal time.

This confirmed the unsuitability of the mean solar second of Universal Time as a measure of time interval for the most precise purposes.

* 1879 – Sandford Fleming first proposes adoption of Universal Standard Time at a meeting of the Royal Canadian Institute.

Many almanacs list full moons not just by date, but by their exact time as well, usually in Coordinated Universal Time ( UTC ).

where d is the number of days since 1 January 2000 00: 00: 00 in the Terrestrial Time scale used in astronomical ephemerides ; for Universal Time ( UT ) add the following approximate correction to d:

It is arguably the same as Coordinated Universal Time ( UTC ) and when this is viewed as a time zone the name Greenwich Mean Time is especially used by bodies connected with the United Kingdom, such as the BBC World Service, the Royal Navy, the Met Office and others particularly in Arab countries, such as the Middle East Broadcasting Center and OSN.

Before the introduction of UTC on 1 January 1972 Greenwich Mean Time ( also known as Zulu time ) was the same as Universal Time ( UT ) which is a standard astronomical concept used in many technical fields.

On 1 January 1972, GMT was replaced as the international time reference by Coordinated Universal Time, maintained by an ensemble of atomic clocks around the world.

It also provides for a standardized method of communicating time-based information across time zones by attaching an offset to Coordinated Universal Time ( UTC ).

* 1827 – Sir Sandford Fleming, Canadian engineer ; introduced Universal Standard Time ( d. 1915 )

Longitude at a point may be determined by calculating the time difference between that at its location and Coordinated Universal Time ( UTC ).

The details are more complex than described here: see the articles on Universal Time and on the equation of time for more details.

To obtain this moment expressed in Universal Time ( UT, world clock time ), add the result of following approximate correction to the result d obtained above:

GMT either by that name or as ' mean time at Greenwich ' used to be an international time standard, but is no longer so ; it was initially renamed in 1928 as Universal Time ( UT ) ( partly as a result of ambiguities arising from the changed practice of starting the astronomical day at midnight instead of at noon, adopted as from 1 January 1925 ).

Universal Time ( UT ) is a time scale based on the mean solar day, defined to be as uniform as possible despite variations in Earth's rotation.

Universal Time ( UT ) is a time scale based on the rotation of the Earth.

However, because Universal Time is synchronous with night and day, and more precise atomic-frequency standards drift away from this, UT is still used to produce a correction ( called a leap second ) to atomic time, in order to obtain a broadcast form of civil time that carries atomic frequency.

GMT is now often called Universal Time, which is now calculated from observations of extra-galactic radio sources, and then converted into several forms, including UT0 ( UT at the remote observatory ), UT1 ( UT corrected for polar motion ), and UTC ( UT in discrete SI seconds within 0. 9 s of UT1 ).

Alternatively, the Universal Translator is capable of interpreting intentions, so when a speaker intends their speech to be projected natively, the UT passes the speech through untranslated.

The diurnal behavior of the vertical electric field shows three distinct maxima, associated with the three " hot spots " of planetary lightning activity: 9 UT ( Universal Time ) peak, linked to the increased thunderstorm activity from south-east Asia ; 14 UT peak associated with the peak in African lightning activity ; and the 20 UT peak resulting for the increase in lightning activity in South America.

After 1884, mean solar time at Greenwich became a standard, later named Universal Time ( UT ).

At the International Astronomical Union ( IAU ) meeting in Dublin in 1955, he had proposed the system of distinguishing between variants of Universal Time, as UT0 ( UT as directly observed ), UT1 ( reduced to invariable meridian by correcting to remove effect of polar motion ) and UT2 ( further corrected to remove ( extrapolated ) seasonal variation in earth rotation rate ), a system which remains in some use today.

MTC is a proposed Mars analog to Universal Time ( UT ) on Earth.

The name " MTC " is intended to parallel Coordinated Universal Time ( UTC ), but this is somewhat misleading: what distinguishes UTC from other forms of UT is its leap seconds, but MTC does not use any such scheme.

Patterson claimed to have screened the film for unnamed technicians " in the special effects department at Universal Studios in Hollywood ... Their conclusion was: ' We could try ( faking it ), but we would have to create a completely new system of artificial muscles and find an actor who could be trained to walk like that.

Brooks ' style was generally slapstick and zany in nature, often parodying film styles and genres, including Universal horror films ( Young Frankenstein ), westerns ( Blazing Saddles ) and Hitchcock films ( High Anxiety ).

DDC's numbers formed the basis of the more expressive but complex Universal Decimal Classification ( UDC ), which combines the basic Dewey numbers with selected punctuation marks ( comma, colon, parentheses, etc .).

Other models are the Auto Union 1000 S Sedán ( 21. 797 made until 1969 ), the Auto Union 1000 Universal S ( 6. 396 made until 1969 ).

However, Chambers ' Cyclopaedia, or Universal Dictionary of Arts and Sciences ( 1728 ), and the Encyclopédie of Diderot and D ' Alembert ( 1751 onwards ), as well as Encyclopædia Britannica and the Conversations-Lexikon, were the first to realize the form we would recognize today, with a comprehensive scope of topics, discussed in depth and organized in an accessible, systematic method.

The most commonly used model for predicting soil loss from water erosion is the Universal Soil Loss Equation ( USLE ), which estimates the average annual soil loss as:

In 2011, Academy Award-nominated director Sam Green ( The Weather Underground ), released a new documentary about Esperanto titled The Universal Language ( La Universala Lingvo.

Giving Expressionist-affiliated filmmakers particularly free stylistic rein were Universal horror pictures such as Dracula ( 1931 ), The Mummy ( 1932 )— the former photographed and the latter directed by the Berlin-trained Karl Freund — and The Black Cat ( 1934 ), directed by Austrian émigré Edgar G. Ulmer.

The Universal horror that comes closest to noir, both in story and sensibility, however, is The Invisible Man ( 1933 ), directed by Englishman James Whale and photographed by American Arthur Edeson.

In addition to The Killers, Burt Lancaster's debut and a Hellinger / Universal coproduction, Siodmak's other important contributions to the genre include 1944's Phantom Lady ( a top-of-the-line B and Woolrich adaptation ), the ironically titled Christmas Holiday ( 1944 ), and Cry of the City ( 1948 ).
