milliseconds to time in javascript

Question

I have this function which formats seconds to time

 function secondsToTime(secs){
    var hours = Math.floor(secs / (60 * 60));
    var divisor_for_minutes          


        

Answer 1

Why not use the Date object like this?

let getTime = (milli) => {
  let time = new Date(milli);
  let hours = time.getUTCHours();
  let minutes = time.getUTCMinutes();
  let seconds = time.getUTCSeconds();
  let milliseconds = time.getUTCMilliseconds();
  return hours + ":" + minutes + ":" + seconds + ":" + milliseconds;
}

Answer 2

function msToTime(s) {

  var d = new Date(s); 
  var datestring = ("0" + d.getDate()).slice(-2) + "-" + ("0"+(d.getMonth()+1)).slice(-2) + "-" +
    d.getFullYear() + " " 
    + ("0" + d.getHours()).slice(-2) 
    + ":" + ("0" + d.getMinutes()).slice(-2)
    + ":" + ("0" + d.getSeconds()).slice(-2)
    +"."+d.getMilliseconds();

  return datestring;      

}

output 16-10-2019 18:55:32.605

Answer 3

const monthNames = ["Jan", "Feb", "Mar", "Apr", "May", "Jun",
 "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"
];
export function getFormattedDateAndTime(startDate) {
    if (startDate != null) {
      var launchDate = new Date(startDate);
       var day = launchDate.getUTCDate();
      var month = monthNames[launchDate.getMonth()];
      var year = launchDate.getFullYear(); 
      var min = launchDate.getMinutes();
      var hour = launchDate.getHours();
      var time = launchDate.toLocaleString('en-US', { hour: 'numeric', minute: 'numeric', hour12: true });

      return  day + " " + month + " " + year + " - " + time + ""  ;
    }
    return "";
   }

Answer 4

function millisecondsToTime(milli)
{
      var milliseconds = milli % 1000;
      var seconds = Math.floor((milli / 1000) % 60);
      var minutes = Math.floor((milli / (60 * 1000)) % 60);

      return minutes + ":" + seconds + "." + milliseconds;
}

var 
         /**

         * @param {Number} ms

         * @return  {Integer} timeStruct.m minutes
         * @return  {Integer} timeStruct.s seconds
         */
        millisecToTimeStruct = function (ms) {
            var d, h, m, s;
            if (isNaN(ms)) {
                return {};
            }
            d = ms / (1000 * 60 * 60 * 24);
            h = (d - ~~d) * 24;
            m = (h - ~~h) * 60;
            s = (m - ~~m) * 60;
            return {d: ~~d, h: ~~h, m: ~~m, s: ~~s};
        },

        toFormattedStr = function(tStruct){
           var res = '';
           if (typeof tStruct === 'object'){
               res += tStruct.m + ' min. ' + tStruct.s + ' sec.';
           }
           return res;
        };

// client code:
var
        ms = new Date().getTime(),
        timeStruct = millisecToTimeStruct(ms),
        formattedString = toFormattedStr(timeStruct);
alert(formattedString);

Answer 6

var secondsToTime = function(duration) {
  var date = new Date(duration);

  return "%hours:%minutes:%seconds:%milliseconds"
    .replace('%hours', date.getHours())
    .replace('%minutes', date.getMinutes())
    .replace('%seconds', date.getSeconds())
    .replace('%milliseconds', date.getMilliseconds());
}
