Astra time display....how to set it?

Hello from the U.S. We are getting the Opel/Vauxhall Astra here in a few months as a Saturn. Some people here are peeing their pants because the time display is in 24hr mode (what some of us refer to as Military time). I don't have a problem with it, but I'd like to ask if it is possible to change that to a 12hr clock, and if so...how? Any help would be greatly appreciated. Thanks

Yes, it can be set into 12 hour time using 'Tech II' OBD software.

Thank you!
