It's not obvious, but SQL Server 2005 Report Builder allows you to use expressions in textboxes on the report surface. You don't get an expression editor, but if you begin a textbox value with '=', it will be evaluated at report processing time. For example, you can add a time / date stamp to a report by using =Globals.ExecutionTime.ToString("f"). Since you can't set the formatting property, you will have to format the string yourself if you don't like the default format.
