Assuming the men both knew each other's code, they find that one of them moves faster. proving time exists. if you are paranoid i could have them each record their respective ids all the way through. but i think you get the point.
maybe you already knew about this. that's fine. but THEY DID NOT!
crojipjip: i made a mistake
crojipjip: well maybe not
crojipjip: you could propose as one of the men that each person had to take their turn once. so surely eventually the guy with more calculations to do will require more time
crojipjip: derp. but time may not be what they call it. just more steps
Actually nope. They don't take turns. no such thing as sharing steps. this does prove time is a matter. this absolutely does suggest time. however small.
