Straigt Javascript time format / update

1: create month converter func 2: create time func 3: create update func 4: create outPut func

    // month converter from index / 0-11 values
function covertMonth(num){
  let months = ['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec'];
  // look into index with num 0-11
  let computedRes = months[num];
  return computedRes;
}

// time func
function Time(){
   // important to get new instant of the Date referrance
  let date = new Date();
  this.time = date.toLocaleTimeString();
  this.year = date.getUTCFullYear();
  this.day = date.getUTCDate();
  this.month = date.getUTCMonth();
  this.currentTime = date.toLocaleTimeString() + ' ' + covertMonth(this.month) + ' ' + this.day + ' ' + this.year;
  return this.currentTime;
}


 function timeOutPut(){
  let where = document.getElementById('some-id');
  where.textContent = Time(); // 1:21:39 AM Dec 17 2017
}

   // run every 5secs
setInterval(timeOutPut, 5000);
