Time, Ephemerides

Scientific paper

Over the past decades, the IAU has repeatedly attempted to correct its definition of the basic fundamental argument used in the ephemerides. Finally, they have defined a time system which is physically possible, according to the accepted standard theory of gravitation: TCB (``Barycentric Coordinate Time''). Ironically, this time scale is mathematically and physically equivalent to Teph, the time scale that has been used by JPL and by MIT (the group later went to CfA) in their ephemeris creation processes since the 1960's. TCB differs from Teph by only a constant offset and a constant rate. As such, TCB provides an equivalent alternative to Teph, but it does not allow increased accuracy as others have implied.
