I didn't mean to draw a contrary conclusion based on it, and perhaps I still don't understand your complete point.

I got a smart phone, found a clock that would display tenth's of a second(would have preferred hundredths), and took pictures of it at high shutter speed, then read them off the image itself. I don't completely trust the camera clock, as not sure exactly how it deals with the pipeline inside of it (i.e. the buffer) and when the time is attached.
