JavaScript seconds to time string with format hh:mm:ss

String.prototype.toHHMMSS = function () {
    var sec_num = parseInt(this, 10); // don't forget the second param
    var hours   = Math.floor(sec_num / 3600);
    var minutes = Math.floor((sec_num - (hours * 3600)) / 60);
    var seconds = sec_num - (hours * 3600) - (minutes * 60);

    if (hours   < 10) {hours   = "0"+hours;}
    if (minutes < 10) {minutes = "0"+minutes;}
    if (seconds < 10) {seconds = "0"+seconds;}
    return hours+':'+minutes+':'+seconds;
}

You can use it now like:

alert("5678".toHHMMSS());

Working snippet:

String.prototype.toHHMMSS = function () {    var sec_num = parseInt(this, 10); // don't forget the second param    var hours   = Math.floor(sec_num / 3600);    var minutes = Math.floor((sec_num - (hours * 3600)) / 60);    var seconds = sec_num - (hours * 3600) - (minutes * 60);
    if (hours   < 10) {hours   = "0"+hours;}    if (minutes < 10) {minutes = "0"+minutes;}    if (seconds < 10) {seconds = "0"+seconds;}    return hours + ':' + minutes + ':' + seconds;}    console.log("5678".toHHMMSS());

convert time string to seconds in javascript/jquery

I know this will not sound good for some, but if you don't want to use a plugin like moment.js. You could parse it like this (only for format dd'd' hh:mm:ss):

var days = parseInt(time.split('d ')[0]);
var hours = parseInt(time.split('d ')[1].split(":")[0]);
var mins = parseInt(time.split('d ')[1].split(":")[1]);
var secs = parseInt(time.split('d ')[1].split(":")[2]);

hours += days * 24;
mins += hours * 60;
secs += mins * 60;

secs will be the total

Convert seconds to HH-MM-SS with JavaScript?

Updated (2020):

Please use @Frank's one line solution:

new Date(SECONDS * 1000).toISOString().substring(11, 16)

If SECONDS<3600 and if you want to show only MM:SS then use below code:

new Date(SECONDS * 1000).toISOString().substring(14, 19)

It is by far the best solution.

Old answer:

Use the Moment.js library.

    hour = parseInt(pieces[0], 10);
    minute = parseInt(pieces[1], 10);
    second = parseInt(pieces[2], 10);
