gnsstk::EphTime Class Reference

Detailed Description

Todo:

Make this class inherit from TimeTag like all the others.

Class implementing date+time, only in formats applicable solar system ephemeris and earth orientation, namely UTC, TT and TDB. Conversion to and from CommonTime is implicit through casts defined here.
