Its a well known fact that everyone who's late to work because his iPhone alarm didn't go off, will get a signed letter from Steve Jobs which permits them to be late for work.
Its not the iPhone's fault of course, its just that Steve decided to change the world's time to a time which will allow him to earn more money in some manner. We all just don't know it yet, as we're not advanced enough to understand it.

Apple invented time. Again.
