Ephemeris from Pulsar by Ladd Allen Doane
A modern relativistic coordinate time scale, implemented by the JPL ephemeris time argument Teph, in a series of numerically integrated Development Ephemerides. Among them is the DE405 ephemeris in widespread current use. The time scale represented by Teph is closely related to, but distinct (by an offset and constant rate) from, the TCB time scale currently adopted as a standard by the IAU.
Transcendental rhythms and soundscapes hover over one another causing fractions of time to stand still.
