It looks like we lost our regular AIX buildbot worker in early 2017, so any
builds since then have been ad hoc/infrequent.
That said, I think we're happy to help work through any issues that have
arisen since then and get things back into a usable state on AIX.

[obligatory note that kauth is woefully insecure and should only be used if
you have compatibility requirements with legacy systems that cannot be
upgraded]

That looks like some fallout from https://gerrit.openafs.org/#/c/14238/ and
given the lack of any remark about testing on AIX in the review notes, I'm
more inclined to think it's an issue with the OpenAFS code than your setup.

What does curtime() look like on your system?
We just need a way to get the current time in seconds+microseconds
precision (converting from, e.g., nanoseconds if needed).  We may have just
typo'd something in the src/afs/AIX/osi_machdep.h chunk, for all I know.

Thanks,

Ben

P.S. If you think you might be able to contribute some resources to have a
regular AIX buildbot worker again, we'd be delighted to talk about that!
