I want to convert a duration of time, i.e., number of seconds to colon-separated time string (hh:mm:ss)

I found some useful answers here but they all talk about converting to x hours and x minutes format.

So is there a tiny snippet that does this in jQuery or just raw JavaScript?

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());

Current JavaScript

From ES6 on you could use template strings:

let soMany = 10;
console.log(`This is ${soMany} times easier!`);
// "This is 10 times easier!

See Kim's answer below for details.


Older answer

Try sprintf() for JavaScript.


If you really want to do a simple format method on your own, don’t do the replacements successively but do them simultaneously.

Because most of the other proposals that are mentioned fail when a replace string of previous replacement does also contain a format sequence like this:

"{0}{1}".format("{1}", "{0}")

Normally you would expect the output to be {1}{0} but the actual output is {1}{1}. So do a simultaneously replacement instead like in fearphage’s suggestion.

Updated (2020):

Please use @Frank's one line solution:

new Date(SECONDS * 1000).toISOString().substr(11, 8)

It is by far the best solution.


Old answer:

Use the Moment.js library.

This might help

using System;
using System.Globalization;

namespace ConsoleApplication7
{
    class Program
    {
        static void Main(string[] args)
        {
            DateTime d = DateTime.ParseExact("124510", "hhmmss", CultureInfo.InvariantCulture);

            Console.WriteLine("Total Seconds: " + d.TimeOfDay.TotalSeconds);

            Console.ReadLine();
        }
    }
}

Note this will not handle 24HR times, to parse times in 24HR format you should use the pattern HHmmss.
