International Atomic Time ( TAI, from the French name Temps atomique international ) is a high-precision atomic coordinate time standard based on the notional passage of proper time on Earth's geoid.

The SI second was defined in terms of the caesium atom in 1967, and in 1971 it was renamed International Atomic Time ( TAI ).

The International Time Bureau ( BIH ) began a time scale, T < sub > m </ sub > or AM, in July 1955, using both local caesium clocks and comparisons to distant clocks using the phase of VLF radio signals.

While TT is strictly uniform ( being based on the SI second, every second is the same as every other second ), it is in practice realised by International Atomic Time ( TAI ) with an accuracy of about 1: 10 < small >< sup > 14 </ sup ></ small >.

At approximately 9: 40 AM Eastern Daylight Time on April 27, 2012 Enterprise took off from Dulles International Airport en-route to a fly-by over the Hudson River, New York's JFK International Airport, the Statue of Liberty, the George Washington and Verrazano-Narrows Bridges, and several other landmarks in the city ; in an approximately 45-minute " final tour ".

At 11: 23 AM Eastern Daylight Time Enterprise touched down at JFK International Airport.

Terrestrial Time ( TT ) is a modern astronomical time standard defined by the International Astronomical Union, primarily for time-measurements of astronomical observations made from the surface of the Earth.

TT indirectly underlies UTC, via International Atomic Time ( TAI ).

* To millisecond accuracy, TT runs parallel to the atomic timescale ( International Atomic Time, TAI ) maintained by the BIPM.

A definition of a terrestrial time standard was adopted by the International Astronomical Union ( IAU ) in 1976 at its XVI General Assembly, and later named Terrestrial Dynamical Time ( TDT ).

More precisely, it was defined that TT instant 1977-01-01T00: 00: 32. 184 exactly and TCG instant 1977-01-01T00: 00: 32. 184 exactly correspond to the International Atomic Time ( TAI ) instant 1977-01-01T00: 00: 00. 000 exactly.

* June 30 – The International Time Bureau adds the first leap second ( 23: 59: 60 ) to Coordinated Universal Time ( UTC ) at the end of the month.

Historical Julian dates were recorded relative to GMT or Ephemeris Time, but the International Astronomical Union now recommends that Julian Dates be specified in Terrestrial Time, and that when necessary to specify Julian Dates using a different time scale, that the time scale used be indicated when required, such as JD ( UT1 ).

# January 1, 2000, 11: 59: 27. 816 TAI ( International Atomic Time ).

* Ephemeris Time ( ET ) was from 1952 to 1976 an official time scale standard of the International Astronomical Union ; it was a dynamical time scale based on the orbital motion of the Earth around the Sun, from which the ephemeris second was derived as a defined fraction of the tropical year.

TDT is tied in its rate to the SI second, as is International Atomic Time ( TAI ), but because TAI was somewhat arbitrarily defined at its inception in 1958 to be initially equal to a refined version of UT, TT is offset from TAI, by a constant 32. 184 seconds.

International Atomic Time ( TAI ) is the primary international time standard from which other time standards, including UTC, are calculated.

TAI is kept by the BIPM ( International Bureau of Weights and Measures ), and is based on the combined input of many atomic clocks around the world, each corrected for environmental and relativistic effects.

Nowadays, UT in relation to International Atomic Time ( TAI ) is determined by Very Long Baseline Interferometry ( VLBI ) observations of distant quasars, a method which has an accuracy of microseconds.

The technique is commonly used for creating and distributing standard time scales such as International Atomic Time ( TAI ).

Whereas Unix time is based on Coordinated Universal Time ( UTC ) and is subject to leap seconds, PTP is based on International Atomic Time ( TAI ) and moves forward monotonically.

The 1976 definition of the astronomical unit was incomplete, in particular because it does not specify the frame of reference in which time is to be measured, but proved practical for the calculation of ephemerides: a fuller definition that is consistent with general relativity was proposed, and " vigorous debate " ensued until in August 2012 the International Astronomical Union adopted the current definition of 1 astronomical unit = 149597870700 meters.
