Reminds me of a similar bug in a payment processing system the company I worked for used. Long story short, overflow in Java numerical types (counting milliseconds for durations in weeks...) caused the system to go haywire and charge customers 1000x the normal amount...
It turned out very profitable for the company though. Stonewalling customers and refusing charge backs is too easy. Not picking up the phone is a good business strategy.
