1334 minutes game time

This issue arose fairly recently, and while it doesn't really tamper with gameplay in anyway, I still find it's an interesting issue. It consists of the game timer in the friends list making it appear as though my friend has been playing for 1334 minutes. It only happens with my one friend, and occurs whenever he goes into a game, regardless of whether or not I've restarted my game. This issue also survived a complete game re-installation. Anyone having this happen to them?
