Is "datetime minus datetime" not implemented in PonyORM?

[Elijas]

exc_type = <class 'TypeError'>
args = ("Unsupported operand types 'datetime' and 'datetime' for operation '-' in expression: {EXPR}",)
kwargs = {}

    def throw(exc_type, *args, **kwargs):
        if isinstance(exc_type, Exception):
            assert not args and not kwargs
            exc = exc_type
        else: exc = exc_type(*args, **kwargs)
        exc.__cause__ = None
        try:
            if not (pony.MODE == 'INTERACTIVE' and options.CUT_TRACEBACK):
>               raise exc
E               TypeError: Unsupported operand types 'datetime' and 'datetime' for operation '-' in expression: datetime.utcnow() - car.created_at
