The packs are Precision Timing Systems. When they press a button on the pack, it starts the clock. There is a microphone attached near the whistle that stops the clock on blasts of the whistle. The official chopping in time is responsible for starting the clock, but anyone can start time with a press of a button. As far as how timeouts are timeouts are handled, that is a rulebooks question that I don't have handy.
