The Timer that acts like a heartbeat for the application.

Sets up a @ax-actionscript-book-SimpleClock-com-example-programmingas3-clock-SimpleClock instance.

Called once per second when the Timer event is received.

          {
                  // Updates the clock display.
              face.draw();
