Adding a timestamp when record is first created
I know this is basic, but how do I add a timestamp that would be created automatically when I create a new record so I could do a search for records created within, say, the last month? I wouldn't want the timestamp to update every time the record was altered, I would just want it to be for when it was originally created. Does the timestamp live as a field on the record like other fields? Or, is it invisible?
thank you for your patience with my newbie-ness...
