If no one else steps up, I can look at it. But I doubt I can finish it 
by a1.

I can do datetime.datetime and datetime.date, if no one else already 
has. I think they're just aliases for strftime. Is there any problem 
with re-using the C implemenation exactly?
static PyMethodDef date_methods[] = {
...
	{"strftime", 	(PyCFunction)date_strftime,	METH_VARARGS | METH_KEYWORDS,
	 PyDoc_STR("format -> strftime() style string.")},
	{"__format__", (PyCFunction)date_strftime,	METH_VARARGS | METH_KEYWORDS,
	 PyDoc_STR("Alias for strftime.")},
...
I just want to make sure there's no requirement that the function 
pointer be unique within the array, or anything like that.
