It's probably better to make this an explicit choice.

The DB-API allows the module to make a choice of which implementation
to use. mxDateTime has been the defacto standard for many years, so
there's a lot of code out there relying on it and mxDateTime is
still very much alive.

Database modules are free to support more than just one way to interface
to date/time values in databases, e.g. Unix ticks, time tuples,
strings, mxDateTime, datetime module, custom types, etc. The spec
itself doesn't mandate a default.

You have the same situation for monetary values, decimal values,
blobs and text.
