DeltaT:

Path: Common/Time

--------------------------------------------------------------------------
   Computes the difference between UT1 and TT based on the Julian date.
   This model is based on observations up through 1993 and after that
   is a linear extrapolation. The equation is UT1 = TT - DT.

   If you type DeltaT it will compute dt for the current date and time.

   Since version 1.
--------------------------------------------------------------------------
   Form:
   dt = DeltaT( jd )
--------------------------------------------------------------------------

   ------
   Inputs
   ------
   jd           (1,1) Julian date

   -------
   Outputs
   -------
   dt           (1,1) Time difference
