I installed the Business Starter Kit to use the Event Calendar. Works pretty well for what I need but the iCal downlaods are off in terms of Time and Date. Something to do with the time zone in the .ics file I am sure but I cannot find where or how to change it.

I need it to be U.S. Central Standard Time.

Here is the .ics from a test event I put in.
