Description

Call JulianDateToDateTime to convert a Julian date to the corresponding TDateTime value.

The Julian date is the number of days, including fractional days, since 4713 BC January 1, Greenwich noon. Julian dates are used by astronomers and others who need an unambiguous dating system based on continuing day counts.

Note: If JulianDateToDateTime can't convert the date specified by AValue, it raises an EConvertError exception.
