Add to date field the default choice of entry added. Also add the default choice of when an entry was updated.
I suggest that the default choices for a date field include the choice of the date that an entry was added or when the entry was updated. This would allow for tracking the date that an entry was first added or when it was updated (both, if two date fields are used). I've used such choices in Smart-List-To-Go database on a Palm PDA.
This is a useful feature
