It seems that if there is a high enough operations per second the tool will return a negative time frame. In case you were wondering this is the theoretical total output possible with the AMD FX 8150 clocked at 3.6 Ghz. (assuming on billion calculations per second per Ghz) Practically you would have to get your OS to recognize it as a quad core to get anywhere close to those numbers. That said it shouldn't be to hard considering the Bulldozer architecture. Either way this is still a bug.
