haha, wow - this is some old code... :)

thanks for the fix -- I tested with your patch and it gives the right numbers with

  var now = Date.now;
  Date.now = function () {
    return now() + 8000;
  };

eventually i'd like to make this more modular by converting it to a component and mounted express app
