## Function result

AValue with replaced parts

## Description

RecodeDateTime 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.

## Errors

If one of the values AYear, AMonth, ADay, AHour, AMinute, ASecond AMilliSecond is not within a valid range (RecodeLeaveFieldAsIs excepted) then an EConvertError exception is raised.
