Daylight Saving

I have my own SQl server and WordPress site hosted. There is a problem with daylight saving on the charts. I have validated the date/time settings on my SQL server and WordPress installation. The query used to obtain the results is working but for some reason the WPBI line chart displays the last data point 1 hour ahead of the current time. This leads me to believe that there must be some code in the plugin that deals with daylight saving that isn’t working properly.
