I depend on the default version that is exposed via the time module when
using Python 2.2 under Solaris 9.

This is the only one that has emerged from a real-life running application.
In fact, this kind of code is our only use of strptime, though after all of
this confusion it may be replaced RSN with something more deterministic.

I'm not sure what else you expect of me. I have an application, some
anecdotal evidence that something is amiss, reported specific test-code that
that demonstrated problem, and encouraged Brett do a bit of digging though
the standards to see if he can improve things.
If you feel that I am being unreasonably vague about what Brett should do,
then you are quite right! I'm burried under a dozen other projects, and in
spite of that, felt it was important to make time to test Python 2.3a1. In
doing so I found one concrete thing wrong with how we used strptime and a
bucket full of things that looked fishy. However, digging through the nooks
and crannies of strptime is not at all important to me, especially when I
have a viable work-around on all platforms that I care about (i.e.,
re-enabling the libc version).
Happy to help, but not expecting the Spanish Inquisition,
