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 )
