When you say that you're using the ITSM report console - do you mean that you're utilizing the SAP Business Objects or Crystal based reports? Is this over the web or through the embedded crystal viewer on the User Tool?
I ask because I've heard of time zone issues with Business Objects - and perhaps that's where the issue lies... For example:
"Impacts to Crystal Reports XI R2 and Crystal Reports XI
The ShiftDateTime formula function will use incorrect DST rules, by default, if none are specified for dates after 2007."
