Talk to your site administrators and check the paperwork. There is NOTHING on a mainframe that indicates when it was installed. If you have proper access, you can find out the last date it was IPLed but that is not the installation date. As far as I know, unless you look at the paperwork that so indicates, there is no way to tell when a particular mainframe was installed.
