const clock = () => {
  var date    = new Date();
  var hours   = date.getHours();
  var minutes = date.getMinutes();
  var seconds = date.getSeconds();
  var midday;

  hours     = updateTime(hours);

  }, 1000);

  //   Good Morning and Good Night Conditions

  if (hours < 12) {
    var greeting = "Good Morning " + name + " Hurry Up!";
  }

  if (hours >= 12 && hours <= 18) {
