So what ? Do an EncodeDate() and you're all set.
That would be a real performance hit (i.e. when sorting by date)
if you have stored dates in year, month, day... format.
Each comparison then needs multiple convertions each time.
Not with ISO date format (yyyy-mm-dd), where a single string compare is
sufficient. But certainly a string compare is more expensive than a
comparison of two Real values.
