Oh wow, I didn't expect such much headaches when I worked on unifiying the code to handle timestamps in the C part of CPython...

> The bug was introduced while trying to support #22117: "Rewrite pytime.h to work on nanoseconds" in reve93eeadef0c3: https://hg.python.org/cpython/rev/e93eeadef0c3

Yeah, the changeset e93eeadef0c3 was the last change to drop the last function of the old PyTime.

Well... in fact, I also had to keep _PyTime_ObjectToTime_t() and _PyTime_ObjectToTimeval() for the exact same reason: support timestamp after the year 2038 on Windows.

Right, the tv_sec field of a timeval structure on Windows has the C type long, whereas it has the type time_t on all other platforms...

I fixed the bug in Python 3.5 and 3.6. Thanks for your bug report. I didn't expect to test year 2038 bug on the latest release, thanks time traveler :-)
