In directory sc8-pr-cvs1:/tmp/cvs-serv10637/python/Lib/test

Modified Files:
	test_datetime.py 
Log Message:
SF bug 680864:  test_datetime fails for non-unix epoch
Apparently MAC OS 9 doesn't have POSIX-conforming timestamps.  A test
fails as a result, but at least for this specific test it's easy enough
to get the POSIX epoch out of it.
