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. -------------------------------------------------------------------------- Form: dt = DeltaT( jd ) -------------------------------------------------------------------------- ------ Inputs ------ jd (1,1) Julian date ------- Outputs ------- dt (1,1) Time difference -------------------------------------------------------------------------- References: U.S. Naval Observatory, MICA, U.S. Naval Observatory Washington, D.C., p.
