also note:

import time tm = time.gmtime() tm (2001, 10, 30, 22, 54, 16, 1, 303, 0) tm.tmyear 2001 tm[:6] (2001, 10, 30, 22, 54, 16) tm[3:6] (, , )

in structseq_slice, 

for(i = low; i < high; ++i) {
    PyObject *v = obj->ob_item[i];
    Py_INCREF(v);
    PyTuple_SET_ITEM(np, i, v);
}

should be:

for(i = low; i < high; ++i) {
    PyObject *v = obj->ob_item[i];
    Py_INCREF(v);
    PyTuple_SET_ITEM(np, i-low, v);
}
