[26 Year Gap]

There is only one reference to seeing the 1 second on the clock and that was before A1 inbounded. The rationale for putting the 1 second back up appears to stem from the sound of the whistle coming before the sound of the horn. He does not indicate in the original post that he observed 1 second on the clock prior to the throw-in and that he observed that there was one second at the time he heard the whistle. That is where the definite knowledge is entering into the discussion. The only definite knowledge of the one second on the clock is when the throw-in was about to take place.
