_root.onEnterFrame = function() {
	var date = new Date();
	var sec = date.getSeconds();
	var min = date.getMinutes();
	var hour = date.getHours();
	//
	_root.clock.sec_arrow._rotation = sec*6;
	_root.clock.min_arrow._rotation = min*6;
	_root.clock.hour_arrow._rotation = hour*30;
};

Создаеш 3 обьекта, clock.sec_arrow, clock.min_arrow, clock.hour_arrow. И поворачиваеш их каждую секунду!
