So on a 2 GHz cpu the bound is 0.11 ns > (essentially 0)? I feel like I miscalculated, this error bound is too > good to be true. Never mind, I thought HZ is the cpu speed for some reason. It's the number of jiffies per second, right? So if HZ is 1000, the error bound is actually ~2 ms, which is very large considering that the unit is ns. Right? > > > > > thanks > > -john
