Do it with getTimer:

function startTimer() {
lightMC.gotoAndStop("green");
var started = getTimer();
}
function stopTimer() {
lightMC.gotoAndStop("red");
var stopped = getTimer();
var timeTaken = stopped-started;
trace ("you took "+timeTaken/1000+"seconds to click me");
}

and then a button within lightMC that has the code:

on(release) {
_root.stopTimer();
}
