The model I have, Olympus VN-240PC does not timestamp entry's. It does have a schedule folder that stores entry's by the date recorded and automaticly advances every day. So you can tell what day you recorded something if you use that folder to record into. If you use one of the other three folders which you can customize to whatever you want them to store, you have no date stamp, but I just voice stamp the time and date onto my messages when I feel the need to store a time and date on them. There are more expensive models and one of them may have timestamp. Radio Shack.
