STAYRDY

Hey guys, I'm the owner of a 2011 G25 journey and I'm having trouble changing the timer/mile odometer (Elapsed time and trip odometer) back to a standard 12hour clock like how it was when I first got it. I had it on a 24hr clock(military time) and I pressed and held onto the solid circle switch button and it turned into a elapsed timer/odometer. I know that if I hold onto it, it'll reset but I'm trying to change it back to read the time and not to be a timer. Anyone know how to change it back to a clock? Thanks
