I find date storage a fascinating topic!  This is interesting, because
it would seem that the earliest date available (even though only used
in a 'scholarly' sense), would be 0001-01-01, or January 1, 0001.  If
the Scaliger numbers go back to, basically January 1, -4713, then why
don't the allowed values for a Date field go back that far?
