Point is, you're not allowed to mix TIME and TIMESTAMP arguments with DATEDIFF (DATE and TIMESTAMP is OK though). So, since LAST_MODIFIED_ON is obviously a TIMESTAMP, current_time should be current_timestamp - as in your corrected example.Everything he said; plus, if you are not using Firebird 2.5, the SECOND argument is not supported if LAST_MODIFIED_ON is a DATE type.
