public double JulianDateUT1( double DeltaUT1 )
Public Function JulianDateUT1 ( DeltaUT1 As Double ) As Double
public: virtual double JulianDateUT1( double DeltaUT1 ) sealed
When Delta-UT1 is provided, UT1 is calculated as UT1 = UTC + DeltaUT1. Otherwise, when Delta-UT1 is 0.0, DeltaUT1 is calculated as DeltaUT1 = TT - DeltaT = UTC + ΔAT + 32.184s - DeltaT, where ΔAT is the current number of leap seconds applied to UTC (34 at April 2012, with the 35th being added at the end of June 2012).
Forecast values of DUT1 are published by IERS Bulletin A at http://maia.usno.navy.mil/ser7/ser7.dat
