If you used +-2ns cut, I don't see it being a problem for you. But for  
people analyzing kaon data, I suspect that are using a tighter timing  
cut, and this MC/data resolution discrepancy should be taken into  
consideration, if they are doing any kind of acceptance correction and  
cross section calculations.
