I have a workflow that is supposed to add the current date / time to a field when another field is changed. The field that is supposed to hold the timestamp is a Date / Time field and the trigger is a list/record field. I tried using TO_CHAR(LOCALTIMESTAMP, ‘DD-MON-RR HHMISS PM’) to add the timestamp but that is breaking the list/record field. What would be the correct formula to set a time stamp?
