"hour LEDs increment as the hour progresses" - That is how I have my display. Every 12 minutes one of the 60 LED's representing the hour advances... Instead of having an Hour counter that advances every 60 minutes, my Hour counter advances every 12 minutes. (<-- Actually more complex than that since the time is originating from the Web, and the Hour position needs to be derived based on where the minutes actually are. But for simplistic reasons, the explanation at the beginning will suffice)
