> time.time() can return None, or sometimes NaN

It is possible that it returns NaN, but it cannot return None. time.time() implementation of Python 2.7:

static PyObject *
time_time(PyObject *self, PyObject *unused)
    double secs;
    secs = floattime();
    if (secs == 0.0) {
        return NULL;
    return PyFloat_FromDouble(secs);

FYI I removed the (secs == 0.0) check in Python 3.3 (issue #14368, changeset 206c45f45236), it was a bug. time.time() *cannot* fail, it always return a float.
