• Issue: time.clock_gettime_ns() is too slow #111482

🤖 New build scheduled with the buildbot fleet by @vstinner for commit c7c5479 🤖

The command will test the builders whose names match following regular expression: AIX

The builders matched are:

• PPC64 AIX PR
• PPC64 AIX XLC PR

[vstinner]

Nice, my change fixed the build error on the PPC64 AIX buildbot. Well, there are other errors, but at least, it's possible again to build Python on this buildbot ;-)
