WebApr 11, 2024 · Bases: TimeBase Represent and manipulate times and dates for astronomy. A Time object is initialized with one or more times in the val argument. The input times in val must conform to the specified format and must correspond to the specified time scale. WebTerrestrial TimeTT is the theoretical timescale of apparent geocentric ephemerides of solar system bodies. It applies, in principle, to an Earthbound clock, at sea-level, and for practical purposes it is tied to Atomic Time TAI through the formula TT = TAI + .In practice, therefore, the units of TT are ordinary SI seconds, and
