How to changd report default settings

We just upgraded from Code Collaborator V6 to Collaborator V8.  We have standard reports that we produce every month for metrics.  The date fields in the reports from V6 were in the format MM/DD/YYYY.  The date fields in V8 are in the format "YYYY/MM/DD UTC".  (what is "UTC"?)   Is there a way to reset the date field format in V8 for our reports?
