International Atomic Time (TAI)is a time scale that uses the combined output of some 400 highly precise atomic clocks. It provides the exact speed at which our clocks tick. Universal Time (UT1), also known as astronomical time, refers to the Earth's rotation. It is used to compare the ...
The International Atomic Time TAI is a physically realized time scale which is ultimately used for comparisons between observations and dynamical theories. Its definition should tell unambiguously what an ideal TAI should be. For terrestrial applications, TAI has been defined as a geocentric coordinate ...
