python-dateutil will be updated to version 2.x and there may be changes that affect this package. If python-bloom will work with the newer python-dateutil, you can safely close this bug. If python-bloom really does require python-dateutil 1.5, please use Requires: python-dateutil15 for Fedora versions of the package until it can be updated.
This only does import datetime from dateutil import tz stamp = datetime.datetime.now(tz.tzlocal()) Should be fine with any version of dateutils.
Forgot to add that the tests pass, FWIW since there's just one test case.
