New Apple TV Rentals-Way around the time limit?

There's a simple way of getting around time limit of 24 hours to watch a rented movie.

Simply change the clock on your computer back! The farther you go back, the more time you have to watch it. You can go back as far as days and years. Obviously Apple is going to fix this error, but for now, take your time. 

Of course, you may not always want to be far back in time, so to keep your clock at the current time. . . Change your clock forward in time, rent your movie, and then switch the clock back to the current time.

This is so easy, I kinda feel bad for Apple.
