Examples:

>>> datetime.datetime(2222, 1, 1, microsecond=999999).timestamp()
7952371200.999999
>>> datetime.datetime(3333, 1, 1, microsecond=999999).timestamp()
43012195201.0
>>> datetime.datetime(2567, 1, 1, microsecond=999998).timestamp()
18839548800.999996

I believe this is an issue caused by using `double` in the C implementation.
