Util.Julian_TJD() Method

Converts a UTC Julian Date to a Terrestial Time Julian date (TJD).

Syntax

Util.Julian_TJD(JulianDate)

The method syntax has these parts:

Part	Description
JulianDate (Double)	a UTC Julian date
Return (Double)	the corresponding Terrestrial Julian Date (TJD)

Remarks

A Terrestrial Julian Date (TJD) is a UTC Julian date adjusted for the difference between UTC and Terrestrial Dynamical Time, and is thus suitable for input to solar system orbit calculations. For more information on time scales, see the Util Class documentation.

Note: This does not take into account the difference between UTC and Universal Time, which is at most 0.9 seconds.
