How to convert seconds to HH:mm:ss in moment.js

Question

How can I convert seconds to HH:mm:ss?

At the moment I am using the function below

render: function (data){
     return new Date(data*1000).toTimeString().replace(/.*(\d{2}:\d{2}:\d{2}).*/, "$1");;
}

This works on chrome but in firefox for 12 seconds I get 01:00:12 I would like to use moment.js for cross browser compatibility

I tried this but does not work

render: function (data){
         return moment(data).format('HH:mm:ss');
}

What am I doing wrong?

EDIT

I managed to find a solution without moment.js which is as follow

return (new Date(data * 1000)).toUTCString().match(/(\d\d:\d\d:\d\d)/)[0];

Still curious on how I can do it in moment.js

Answer 1

This is similar to the answer mplungjan referenced from another post, but more concise:

const secs = 456;

const formatted = moment.utc(secs*1000).format('HH:mm:ss');

document.write(formatted);

<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.18.1/moment.min.js"></script>

It suffers from the same caveats, e.g. if seconds exceed one day (86400), you'll not get what you expect.

Answer 2

From this post I would try this to avoid leap issues

moment("2015-01-01").startOf('day')
    .seconds(s)
    .format('H:mm:ss');

I did not run jsPerf, but I would think this is faster than creating new date objects a million times

function pad(num) {
    return ("0"+num).slice(-2);
}
function hhmmss(secs) {
  var minutes = Math.floor(secs / 60);
  secs = secs%60;
  var hours = Math.floor(minutes/60)
  minutes = minutes%60;
  return `${pad(hours)}:${pad(minutes)}:${pad(secs)}`;
  // return pad(hours)+":"+pad(minutes)+":"+pad(secs); for old browsers
}

function pad(num) {
    return ("0"+num).slice(-2);
}
function hhmmss(secs) {
  var minutes = Math.floor(secs / 60);
  secs = secs%60;
  var hours = Math.floor(minutes/60)
  minutes = minutes%60;
  return `${pad(hours)}:${pad(minutes)}:${pad(secs)}`;
  // return pad(hours)+":"+pad(minutes)+":"+pad(secs); for old browsers
}

for (var i=60;i<=60*60*5;i++) {
 document.write(hhmmss(i)+'<br/>');
}


/* 
function show(s) {
  var d = new Date();
  var d1 = new Date(d.getTime()+s*1000);
  var  hms = hhmmss(s);
  return (s+"s = "+ hms + " - "+ Math.floor((d1-d)/1000)+"\n"+d.toString().split("GMT")[0]+"\n"+d1.toString().split("GMT")[0]);
}    
*/

You can use moment-duration-format plugin:

var seconds = 3820;
var duration = moment.duration(seconds, 'seconds');
var formatted = duration.format("hh:mm:ss");
console.log(formatted); // 01:03:40

<!-- moment-duration-format plugin -->

Answer 4

var seconds = 2000 ; // or "2000"
seconds = parseInt(seconds) //because moment js dont know to handle number in string format
var format =  Math.floor(moment.duration(seconds,'seconds').asHours()) + ':' + moment.duration(seconds,'seconds').minutes() + ':' + moment.duration(seconds,'seconds').seconds();
