Tracked Xbox 360 Video games Hours?

Hi there.

There was this twentieth Anniversary factor for Xbox a 12 months in the past or so if i bear in mind appropriately and mine confirmed as most performed recreation Name of Responsibility Trendy Warfare 2 for Xbox 360.
I checked on the Sport's Achievments the place you may usually swap to Stats and see Sport Hours however i dont suppose you may see them on any Xbox 360 Sport, my Query is how did Xbox calculate this and is there a method to see it for myself?
