AResult |
|
Recoded AValue. |
True if the recoding was succesful, False if not.
TryRecodeDateTime replaces selected parts of the timestamp AValue with the date/time values specified in AYear, AMonth, ADay, AHour, AMinute, ASecond and AMilliSecond. If any of these values equals the pre-defined constant RecodeLeaveFieldAsIs, then the corresponding part of the date/time stamp is left untouched.
The resulting date/time is returned in AValue.
The function returns True if the encoding was succesful. It returns False if one of the values AYear, AMonth, ADay, AHour, AMinute, ASecondAMilliSecond is not within a valid range.
