With as much as they talked about the irrevocable destruction of the global ecosystem coming up in a matter of months, and then the constantly rotating day-night cycle, I imagine it would be possible to find out if your in-game time played actually was more or less than that deadline. It would be hilarious if the world was going to end in six months but then the math showed that you actually spent more than a year running around shooting the fins off of robo-pterodactyls.
