It's a problem the visualizer has with the time format of the log.  I fixed the issue by changing the line, hardcoding in +00:00.
Changing
a = [datetime.strptime(parts[0], '%Y-%m-%d %H:%M:%S.%f'),
to
a = [datetime.strptime(parts[0], '%Y-%m-%d %H:%M:%S.%f+00:00'),

in the file /usr/lib/python2.6/site-packages/StarCluster-0.95.5-py2.6.egg/starcluster/balancers/sge/visualizer.py
