Description

The current Spacecraft date and time in International Atomic Time (TAI) in the Modified Julian Date format. The returned value has units of days, measured from January 5, 1941 at 12:00:00.000 TAI.

Changing the value of this property does not cause the Spacecraft's state to be propagated - the Spacecraft's state will not be changed. In order to propagate a Spacecraft to a desired epoch, use the Step command.
