	Note though, SQLite3 only has four native data types: integer, float,
character, blob. It accepts almost anything for a type declaration, and
will map that to the closest internal format (moreover, it will accept any
actual datatype in any actual field -- you can store strings in an integer
field unless the string content IS a representation of an integer in which
case it is turned to binary).

	Regardless of how Python stores a date/datetime/time (well, except for
the floating point C date/time types), it will mostly be kept as a string
representation within SQLite3. 

	It then becomes the responsibility of the converter modules invoked by
the parsing option to identify and format the data. I suspect date and
datetime both parse into the same converter. I'm not sure how it behaves if
one defined converters for date and datetime separately, as I think it uses
substring matching to invoke the converter: a type of date and a type of
datetime would both match a converter for "date" if the date converter is
first in the lookup list.
