Adding creation date/time, maybe in unix timecode format, as well as NetID and Nickname, makes Nickname conflicts statistically almost impossible. You might have 2 new users on the same network, thinking they have the perfect "unique" id, but neither will get the exact same timecode from a unix time() call. Also allows for less chance of ID overlap where a user prefers to not use a nickname.
