Description

Converts a modified Julian date to a TDateTime value.

Call ModifiedJulianDateToDateTime to convert a modified Julian date to the corresponding TDateTime value.

The modified Julian date is the number of days, including fractional days, since Greenwich midnight on November 17, 1858. Modified Julian dates are based on Julian dates, but adjusted to use midnight rather than noon as a starting point and they use a more recent date as a starting point.

Note: If ModifiedJulianDateToDateTime cannot convert the date specified by AValue; it raises an EConvertError exception.
