Interesting Picture

The difference in the clocks will NOT be due to wire length. For a 1/10th second difference, the wire to one display would have to be about 10,000 miles longer than the other one.

What is differnet is the control circuitry and the display technology.

The control circuitry that decodes the control signals from the console could be faster in one clock unit than the other.

The lights that illuminate the numbers could be of a different type...LED, Fluorescent, Incandescent, etc. Those have reaction times that are definitely different. LED's turn on/off nearly instantaneously while incandescents are much slower to change state. I think fluorescent's are also slow.


They are also not necessarily a full 1/10th apart. The could be just 1/1000th of a second apart and the camera captured the image just after one changed and just before the other changedd....giving the impression that they were 1/10th apart...could be 32.999 and 33.000. The only way to really tell would be to have high-speed video....the number of frames they're different times the duration of the frame would give you close to the real difference....if there are enough frames of difference to get a good measurement.
