I was able to reproduce this error by faking a file named
'AEST-10AEDT-11,M10.5.0,M3.5.0' in /usr/share/zoneinfo/ on Mac OS X.
(As far as I know, OSX is not that different from BSD with respect to
basic posix interfaces.)

$ cd /usr/share/zoneinfo/
$ sudo cp EST AEST-10AEDT-11,M10.5.0,M3.5.0

Is it possible that the buildbot has such a file?  What I find strange
is that autoconf logic tests for working tzset using exactly the same
TZ spec:

"""
        putenv("TZ=AEST-10AEDT-11,M10.5.0,M3.5.0");
        tzset();
        if (localtime(&groundhogday)->tm_hour != 11)
            exit(1);
#if HAVE_TZNAME
        if (strcmp(tzname[0], "AEST") || strcmp(tzname[1], "AEDT"))
            exit(1);
#endif
"""  See 'configure' script.

In other words, if TZ=AEST-10AEDT-11,M10.5.0,M3.5.0 breaks tzset, this
should be detected at the configure stage and the tzset tests should
be skipped.   Is there a way to force configure run on the bot?

Issue #13313 has been marked as a duplicate of this issue. Interesting message from flox:

"Maybe it is related.
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=93810

Ambiguous timezone names (AEST vs EST)"

> Is there a way to force configure run on the bot?

./configure is run for each build of each buildbot.

I don't see this issue as a bug in Python, but just that the timezone database is different on some OSes. Can't we just accept both names, AEST and EST? Attached patch changes test_time to tolerate EST name for 'AEST-10AEDT-11,M10.5.0,M3.5.0' ("Victoria") time zone.

Alex ? Florent ?

The FreeBSD 7.2 3.x buildbot is green.

thank you for this fix.
I agree a posteriori.

Hum, it's still not ok:

What is the status of this issue? Was the failure reproduced recently?

Can this be closed as "out of date"?
