We seem to have added tzset() gimmicks to CVS Python. test_time now fails on Windows, simply because time.tzset raises AttributeError there. Now Windows does support tzset(), but not TZ values of the form test_time.test_tzset() is testing, like environ['TZ'] = 'US/Eastern' and environ['TZ'] = 'Australia/Melbourne' The rub here is that I haven't found *any* tzset man pages on the web that claim TZ accepts such values (other than to silently ignore them because they're not in a recognized format). The POSIX defn is typical: http://www.opengroup.org/onlinepubs/007904975/basedefs/xbd_chap08.html and search down for TZ. There's no way to read that as supporting the values we're testing.
