New submission from EGuesnet <etienne.guesnet.exter...@atos.net>:
Hi,
I have an error during regression tests with Python3.8.1 on AIX 6.1 compiled
with GCC 8.3.
It occurs only on 64 bit. Test passes on 32 bit.
```
======================================================================
ERROR: test_add_file_after_2107 (test.test_zipfile.StoredTestsWithSourceFile)

Traceback (most recent call last):

OverflowError: localtime argument out of range
```
The PR associated to the new behavior is:
https://github.com/python/cpython/pull/12726 (new on Python 3.8). Code is AIX
specific. Is the code 32 bit only, or maybe the test was not updated?
-----
I can reproduce the behavior as follow:
```
