The result of which, if the column is to be kept non-NULL, is to either

(1) prevent the user to input those parts of the information that *are* known 
and which *are* useful, or

(2) require the user, in every case of uncertainty, to assign a false value and 
a misleading certainty of some exact date, and with no indication (or 
annotation, much less visual indicator) as to the uncertainty of what has been 
entered.
