public class TTScale extends Object implements TimeScale
Terrestrial Time as defined by IAU(1991) recommendation IV.Coordinate time at the surface of the Earth. IT is the successor of Ephemeris Time TE.
By convention, TT = TAI + 32.184 s.
This is intended to be accessed thanks to the
TimeScalesFactory
class, so there is no public constructor.- Author:
