Sets or returns the Julian date on the UTC timescale for which the transform will be made

Namespace: ASCOM.Astrometry.Transform
Assembly: ASCOM.Astrometry (in ASCOM.Astrometry.dll) Version: (
public double JulianDateUTC { get; set; }

Property Value

Type: Double
Julian date (UTC) of the transform

Return Value

Type: Double
UTC Julian date that will be used by Transform or zero if the PC's current clock value will be used to calculate the Julian date.
Introduced in April 2014 as an alternative to JulianDateTT. Only one of JulianDateTT or JulianDateUTC needs to be set. Use whichever is more readily available, there is no need to set both values. Transform will use the last set value of either JulianDateTT or JulianDateUTC as the basis for its calculations.
