That worked! It didn't work on the server based report writer but worked fine with the web based report writer. Also something is a little weird with the output of the report:
2/1/2014 12:00:00 AM
2/1/2014 12:59:59 AM <--------
2/1/2014 2:00:00 AM
2/1/2014 3:00:00 AM
2/1/2014 3:59:59 AM <-------
Every couple of hours it displays one minute before the hour. I don't think it really impacts what i want from this report just thought it was weird.
