 I'm getting an exception during p4 polling:

 {{{
         Traceback (most recent call last):

             when = when.astimezone(dateutil.tz.tzlocal())
         exceptions.AttributeError: 'module' object has no attribute 'tz'
 }}}

 This looks like it was dealt with already here:

 http://trac.buildbot.net/ticket/2834

 But I've come across it in 0.8.12, python 2.7 32bit, windows.

 The fix is easy, just append .tz to import dateutil on line 21
