Not so stupid, really.  I did put an "echo TZ" into the log, and guess
what?  The uuxqt wrapper itself was being called with TZ unset.  (The
example log I gave might have given the impression that the one uuxqt
that worked and another that failed were from the same invocation of the
uuxqt wrapper - they weren't).  I don't know why or how it was called
with TZ unset at this point, because it is always exec'ed from uucico,
and all my scripts (uushell, demons, etc.) have TZ set.  One thing I
just noticed is that your wrapper script doesn't set TZ!  I guess I had
just assumed that it did, and one of your postings also implied this.

So why is TZ not set? Looking back through my files, I found:

I'm afraid I don't quite understand the reasoning for this - why doesn't
TZ=`/bin/cat /etc/TIMEZONE` work if you have /etc/TIMEZONE configured?
Is this the cause of my problem?  At any rate, I've put TZ=EST5EDT in
the uuxqt wrapper and it's fixed.
