This works if the user calls time.gmtime(None), but it fails for time.gmtime(). It seems that in that case my C converter function is never called.
What's the trick that I'm missing? /*[clinic input] time.gmtime [ seconds: timet ] / Ahh, interesting. So this works, but now the C default is evaluated even if the user passed an argument (so that answers my question about decreased performance in the other subthread). The generated code is:
Don't use time(NULL) as C default. Instead check group_right_1 and call time(NULL) explicitly.
time_gmtime_impl(PyModuleDef *module, int group_right_1, time_t seconds) { if (!group_right_1) seconds = time(NULL); ... }
