How to format $.now() with Jquery

$.now() gives me the time as miliseconds. I need to show it something like hh:mm:ss

$ .now ()는 시간을 밀리 초 단위로 제공합니다. hh : mm : ss와 같이 표시해야합니다.

How to format $.now() with Jquery

function formatTimeOfDay(millisSinceEpoch) {
  var secondsSinceEpoch = (millisSinceEpoch / 1000) | 0;
  var secondsInDay = ((secondsSinceEpoch % 86400) + 86400) % 86400;
  var seconds = secondsInDay % 60;
  var minutes = ((secondsInDay / 60) | 0) % 60;
  var hours = (secondsInDay / 3600) | 0;
  return hours + (minutes < 10 ? ":0" : ":")
      + minutes + (seconds < 10 ? ":0" : ":")
      + seconds;
}
