Seems to be a bug.  I can duplicate the
problem here (Python 2.4.3, Red Hat Desktop release 4).

I do see the correct output, however, if I pass just
the format string to strftime:

>>> print time.strftime("%Y-%m-%d %H:%M:%S %Z %z")
2007-02-21 18:42:03 PST -0800

>>> print time.strftime("%Y-%m-%d %H:%M:%S %Z %z", time.localtime())
2007-02-21 18:42:11 PST +0000
