Note that the time scale that is the basis for Julian dates is Universal Time, and that 0h UT corresponds to a Julian date fraction of 0.5.
Date fields in JD Edwards World files are stored in the Julian format.
Program X0028 converts these dates into the Gregorian format so they are easily recognized in World software applications.
Julian dates are widely used as time variables within astronomical software.
Typically, a 64-bit floating point (double precision) variable can represent an epoch expressed as a Julian date to about 1 millisecond precision.
They are also useful when viewing Julian date fields in applications outside of JD Edwards World that do not convert Julian to Gregorian.
