Answer 1

The moment-duration-format plugin can assist you with this.

// your input
var duration_seconds = 86485;

// create a moment-duration object
var duration = moment.duration(duration_seconds, 'seconds');

// format the object with a string
var formatted = duration.format('h[h] m[m] s[s]');

// displaying the output here
document.getElementById('output').innerHTML = formatted;

Note that by default it will omit units that are not relevant, so if your input is 3, it's just going to say "3s", not "0h 0m 3s".

If you want to change this behavior, set trim:false, per the documentation. For example, to get the format you mentioned in comments, use:

.format('hh:mm:ss', { trim: false })
