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());

You can manage to do this without any external JS library with the help of JS Date method like following:

var date = new Date(0);
date.setSeconds(45); // specify value for SECONDS here
var timeString = date.toISOString().substring(11, 19);
console.log(timeString)

To get the time part in the format hh:MM:ss, you can use this regular expression:

(This was mentioned above in same post by someone, thanks for that.)

    var myDate = new Date().toTimeString().replace(/.*(\d{2}:\d{2}:\d{2}).*/, "$1");
    console.log(myDate)

I recommend ordinary javascript, using the Date object. (For a shorter solution, using toTimeString, see the second code snippet.)

var seconds = 9999;
// multiply by 1000 because Date() requires miliseconds
var date = new Date(seconds * 1000);
var hh = date.getUTCHours();
var mm = date.getUTCMinutes();
var ss = date.getSeconds();
// If you were building a timestamp instead of a duration, you would uncomment the following line to get 12-hour (not 24) time
// if (hh > 12) {hh = hh % 12;}
// These lines ensure you have two-digits
if (hh < 10) {hh = "0"+hh;}
if (mm < 10) {mm = "0"+mm;}
if (ss < 10) {ss = "0"+ss;}
// This formats your string to HH:MM:SS
var t = hh+":"+mm+":"+ss;
document.write(t);

(Of course, the Date object created will have an actual date associated with it, but that data is extraneous, so for these purposes, you don't have to worry about it.)

---

Edit (short solution):

Make use of the toTimeString function and split on the whitespace:

var seconds = 9999; // Some arbitrary value
var date = new Date(seconds * 1000); // multiply by 1000 because Date() requires miliseconds
var timeStr = date.toTimeString().split(' ')[0];

toTimeString gives '16:54:58 GMT-0800 (PST)', and splitting on the first whitespace gives '16:54:58'.

Here's my take on it:

function formatTime(ms: number) {
  const seconds = Math.floor(Math.abs(ms / 1000))
  const h = Math.floor(seconds / 3600)
  const m = Math.floor((seconds % 3600) / 60)
  const s = Math.round(seconds % 60)
  const t = [h, m > 9 ? m : h ? '0' + m : m || '0', s > 9 ? s : '0' + s]
    .filter(Boolean)
    .join(':')
  return ms < 0 && seconds ? `-${t}` : t
}

Expected results:

import assert from 'assert'
assert.equal(formatTime(0), '0:00')
assert.equal(formatTime(1_000), '0:01')
assert.equal(formatTime(599_000), '9:59')
assert.equal(formatTime(600_000), '10:00')
assert.equal(formatTime(3600_000), '1:00:00')
assert.equal(formatTime(360009_000), '100:00:09')
assert.equal(formatTime(200), '0:00')
assert.equal(formatTime(-200), '0:00')
assert.equal(formatTime(-1_000), '-0:01')

A Google search turned up this result:

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

    var divisor_for_minutes = secs % (60 * 60);
    var minutes = Math.floor(divisor_for_minutes / 60);

    var divisor_for_seconds = divisor_for_minutes % 60;
    var seconds = Math.ceil(divisor_for_seconds);

    var obj = {
        "h": hours,
        "m": minutes,
        "s": seconds
    };
    return obj;
}

function formatTime(seconds) {
    return [
        parseInt(seconds / 60 / 60),
        parseInt(seconds / 60 % 60),
        parseInt(seconds % 60)
    ]
        .join(":")
        .replace(/\b(\d)\b/g, "0$1")
}

Variation on a theme. Handles single digit seconds a little differently

seconds2time(0)  ->  "0s" 
seconds2time(59) -> "59s" 
seconds2time(60) -> "1:00" 
seconds2time(1000) -> "16:40" 
seconds2time(4000) -> "1:06:40"

function seconds2time (seconds) {
    var hours   = Math.floor(seconds / 3600);
    var minutes = Math.floor((seconds - (hours * 3600)) / 60);
    var seconds = seconds - (hours * 3600) - (minutes * 60);
    var time = "";

    if (hours != 0) {
      time = hours+":";
    }
    if (minutes != 0 || time !== "") {
      minutes = (minutes < 10 && time !== "") ? "0"+minutes : String(minutes);
      time += minutes+":";
    }
    if (time === "") {
      time = seconds+"s";
    }
    else {
      time += (seconds < 10) ? "0"+seconds : String(seconds);
    }
    return time;
}

Here is an example of using Date.prototype.toLocaleTimeString(). I chose GB as the language, because the US shows a 24 instead of a 00 for the initial hour. Furthermore, I chose Etc/UTC as the time zone, because UTC is aliased to it in the list of tz database time zones.

const formatTime = (seconds) =>
  new Date(seconds * 1000).toLocaleTimeString('en-GB', {
    timeZone:'Etc/UTC',
    hour12: false,
    hour: '2-digit',
    minute: '2-digit',
    second: '2-digit'
  });

console.log(formatTime(75)); // 00:01:15

.as-console-wrapper { top: 0; max-height: 100% !important; }

Here is the same example, but with Intl.DateTimeFormat. This variant lets you instantiate a reusable formatter object, which is more performant.

const dateFormatter = new Intl.DateTimeFormat('en-GB', {
  timeZone:'Etc/UTC',
  hour12: false,
  hour: '2-digit',
  minute: '2-digit',
  second: '2-digit'
});

const formatTime = (seconds) => dateFormatter.format(new Date(seconds * 1000));

console.log(formatTime(75)); // 00:01:15

.as-console-wrapper { top: 0; max-height: 100% !important; }

Using the amazing moment.js library:

function humanizeDuration(input, units ) { 
  // units is a string with possible values of y, M, w, d, h, m, s, ms
  var duration = moment().startOf('day').add(units, input),
    format = "";

  if(duration.hour() > 0){ format += "H [hours] "; }

  if(duration.minute() > 0){ format += "m [minutes] "; }

  format += " s [seconds]";

  return duration.format(format);
}

This allows you to specify any duration be it hours, minutes, seconds, mills, and returns a human readable version.

I like the first answer. There some optimisations:

• source data is a Number. additional calculations is not needed.

• much excess computing

Result code:

Number.prototype.toHHMMSS = function () {
    var seconds = Math.floor(this),
        hours = Math.floor(seconds / 3600);
    seconds -= hours*3600;
    var minutes = Math.floor(seconds / 60);
    seconds -= minutes*60;

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

It's pretty easy,

function toTimeString(seconds) {
  return (new Date(seconds * 1000)).toUTCString().match(/(\d\d:\d\d:\d\d)/)[0];
}

new Date().toString().split(" ")[4];

result 15:08:03

Easiest way to do it.

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

s2t=function (t){
  return parseInt(t/86400)+'d '+(new Date(t%86400*1000)).toUTCString().replace(/.*(\d{2}):(\d{2}):(\d{2}).*/, "$1h $2m $3s");
}

s2t(123456);

result:

1d 10h 17m 36s

I liked Webjins answer the most, so i extended it to display days with a d suffix, made display conditional and included a s suffix on plain seconds:

function sec2str(t){
    var d = Math.floor(t/86400),
        h = ('0'+Math.floor(t/3600) % 24).slice(-2),
        m = ('0'+Math.floor(t/60)%60).slice(-2),
        s = ('0' + t % 60).slice(-2);
    return (d>0?d+'d ':'')+(h>0?h+':':'')+(m>0?m+':':'')+(t>60?s:s+'s');
}

returns "3d 16:32:12" or "16:32:12" or "32:12" or "12s"

I loved Powtac's answer, but I wanted to use it in angular.js, so I created a filter using his code.

.filter('HHMMSS', ['$filter', function ($filter) {
    return function (input, decimals) {
        var sec_num = parseInt(input, 10),
            decimal = parseFloat(input) - sec_num,
            hours   = Math.floor(sec_num / 3600),
            minutes = Math.floor((sec_num - (hours * 3600)) / 60),
            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;}
        var time    = hours+':'+minutes+':'+seconds;
        if (decimals > 0) {
            time += '.' + $filter('number')(decimal, decimals).substr(2);
        }
        return time;
    };
}])

It's functionally identical, except that I added in an optional decimals field to display fractional seconds. Use it like you would any other filter:

{{ elapsedTime | HHMMSS }} displays: 01:23:45

{{ elapsedTime | HHMMSS : 3 }} displays: 01:23:45.678

The most general answer to this is

function hms(seconds) {
  return [3600, 60]
    .reduceRight(
      (p, b) => r => [Math.floor(r / b)].concat(p(r % b)),
      r => [r]
    )(seconds)
    .map(a => a.toString().padStart(2, '0'))
    .join(':');
}

Some example outputs:

> hms(0)
< "00:00:00"

> hms(5)
< "00:00:05"

> hms(60)
< "00:01:00"

> hms(3785)
< "01:03:05"

> hms(37850)
< "10:30:50"

> hms(378500)
< "105:08:20"

Here is yet another version, which handles days also:

function FormatSecondsAsDurationString( seconds )
{
    var s = "";

    var days = Math.floor( ( seconds / 3600 ) / 24 );
    if ( days >= 1 )
    {
        s += days.toString() + " day" + ( ( days == 1 ) ? "" : "s" ) + " + ";
        seconds -= days * 24 * 3600;
    }

    var hours = Math.floor( seconds / 3600 );
    s += GetPaddedIntString( hours.toString(), 2 ) + ":";
    seconds -= hours * 3600;

    var minutes = Math.floor( seconds / 60 );
    s += GetPaddedIntString( minutes.toString(), 2 ) + ":";
    seconds -= minutes * 60;

    s += GetPaddedIntString( Math.floor( seconds ).toString(), 2 );

    return s;
}

function GetPaddedIntString( n, numDigits )
{
    var nPadded = n;
    for ( ; nPadded.length < numDigits ; )
    {
        nPadded = "0" + nPadded;
    }

    return nPadded;
}

function toHHMMSS(seconds) {
    var h, m, s, result='';
    // HOURs
    h = Math.floor(seconds/3600);
    seconds -= h*3600;
    if(h){
        result = h<10 ? '0'+h+':' : h+':';
    }
    // MINUTEs
    m = Math.floor(seconds/60);
    seconds -= m*60;
    result += m<10 ? '0'+m+':' : m+':';
    // SECONDs
    s=seconds%60;
    result += s<10 ? '0'+s : s;
    return result;
}

Examples

    toHHMMSS(111); 
    "01:51"

    toHHMMSS(4444);
    "01:14:04"

    toHHMMSS(33);
    "00:33"

function secToTime(seconds, separator) {
    return [
        parseInt(seconds / 60 / 60),
        parseInt(seconds / 60 % 60),
        parseInt(seconds % 60)
    ].join(separator ? separator : ':')
    .replace(/\b(\d)\b/g, "0$1").replace(/^00\:/,'')
}

You can use it now like:

alert(secToTime("123"));

Working snippet:

function secToTime(seconds, separator) {
return [
    parseInt(seconds / 60 / 60),
    parseInt(seconds / 60 % 60),
    parseInt(seconds % 60)
].join(separator ? separator : ':')
.replace(/\b(\d)\b/g, "0$1").replace(/^00\:/,'')
}

console.log(secToTime("123"));

I think performance wise this is by far the fastest:

var t = 34236; // your seconds
var time = ('0'+Math.floor(t/3600) % 24).slice(-2)+':'+('0'+Math.floor(t/60)%60).slice(-2)+':'+('0' + t % 60).slice(-2)
//would output: 09:30:36

Here's how I did it. It seems to work fairly well, and it's extremely compact. (It uses a lot of ternary operators, though)

function formatTime(seconds) {
  var hh = Math.floor(seconds / 3600),
    mm = Math.floor(seconds / 60) % 60,
    ss = Math.floor(seconds) % 60;
  return (hh ? (hh < 10 ? "0" : "") + hh + ":" : "") + ((mm < 10) && hh ? "0" : "") + mm + ":" + (ss < 10 ? "0" : "") + ss
}

...and for formatting strings...

String.prototype.toHHMMSS = function() {
  formatTime(parseInt(this, 10))
};

You can use the following function to convert time (in seconds) to HH:MM:SS format :

var convertTime = function (input, separator) {
    var pad = function(input) {return input < 10 ? "0" + input : input;};
    return [
        pad(Math.floor(input / 3600)),
        pad(Math.floor(input % 3600 / 60)),
        pad(Math.floor(input % 60)),
    ].join(typeof separator !== 'undefined' ?  separator : ':' );
}

Without passing a separator, it uses : as the (default) separator :

time = convertTime(13551.9941351); // --> OUTPUT = 03:45:51

If you want to use - as a separator, just pass it as the second parameter:

time = convertTime(1126.5135155, '-'); // --> OUTPUT = 00-18-46

---

Demo

var convertTime = function (input, separator) {
    var pad = function(input) {return input < 10 ? "0" + input : input;};
    return [
        pad(Math.floor(input / 3600)),
        pad(Math.floor(input % 3600 / 60)),
        pad(Math.floor(input % 60)),
    ].join(typeof separator !== 'undefined' ?  separator : ':' );
}

document.body.innerHTML = '<pre>' + JSON.stringify({
    5.3515555 : convertTime(5.3515555),
    126.2344452 : convertTime(126.2344452, '-'),
    1156.1535548 : convertTime(1156.1535548, '.'),
    9178.1351559 : convertTime(9178.1351559, ':'),
    13555.3515135 : convertTime(13555.3515135, ',')
}, null, '\t') +  '</pre>';

There's a new method for strings on the block: padStart

const str = '5';
str.padStart(2, '0'); // 05

Here is a sample use case: YouTube durations in 4 lines of JavaScript

A regular expression can be used to match the time substring in the string returned from the toString() method of the Date object, which is formatted as follows: "Thu Jul 05 2012 02:45:12 GMT+0100 (GMT Daylight Time)". Note that this solution uses the time since the epoch: midnight of January 1, 1970. This solution can be a one-liner, though splitting it up makes it much easier to understand.

function secondsToTime(seconds) {
    const start = new Date(1970, 1, 1, 0, 0, 0, 0).getTime();
    const end = new Date(1970, 1, 1, 0, 0, parseInt(seconds), 0).getTime();
    const duration = end - start;

    return new Date(duration).toString().replace(/.*(\d{2}:\d{2}:\d{2}).*/, "$1");
}

Here is a fairly simple solution that rounds to the nearest second!

var returnElapsedTime = function(epoch) {
  //We are assuming that the epoch is in seconds
  var hours = epoch / 3600,
      minutes = (hours % 1) * 60,
      seconds = (minutes % 1) * 60;
  return Math.floor(hours) + ":" + Math.floor(minutes) + ":" + Math.round(seconds);
}

This is one I wrote recently for MM:SS. It's not exact to the question, but it's a different one-liner format.

const time = 60 * 2 + 35; // 2 minutes, 35 seconds
const str = (~~(time / 60) + "").padStart(2, '0') + ":" + (~~((time / 60) % 1 * 60) + "").padStart(2, '0');

str // 02:35

Edit: This was added for variety, but the best solution here is https://stackoverflow.com/a/25279399/639679 below.

This is how i did it

function timeFromSecs(seconds)
{
    return(
    Math.floor(seconds/86400)+'d :'+
    Math.floor(((seconds/86400)%1)*24)+'h : '+
    Math.floor(((seconds/3600)%1)*60)+'m : '+
    Math.round(((seconds/60)%1)*60)+'s');
}

timeFromSecs(22341938) will return '258d 14h 5m 38s'

I'm personally prefer the leading unit (days, hours, minutes) without leading zeros. But seconds should always be leaded by minutes (0:13), this presentation is easily considered as 'duration', without further explanation (marking as min, sec(s), etc.), usable in various languages (internationalization).

    // returns  (-)d.h:mm:ss(.f)
    //          (-)h:mm:ss(.f)
    //          (-)m:ss(.f)
    function formatSeconds (value, fracDigits) {
        var isNegative = false;
        if (isNaN(value)) {
            return value;
        } else if (value < 0) {
            isNegative = true;
            value = Math.abs(value);
        }
        var days = Math.floor(value / 86400);
        value %= 86400;
        var hours = Math.floor(value / 3600);
        value %= 3600;
        var minutes = Math.floor(value / 60);
        var seconds = (value % 60).toFixed(fracDigits || 0);
        if (seconds < 10) {
            seconds = '0' + seconds;
        }

        var res = hours ? (hours + ':' + ('0' + minutes).slice(-2) + ':' + seconds) : (minutes + ':' + seconds);
        if (days) {
            res = days + '.' + res;
        }
        return (isNegative ? ('-' + res) : res);
    }

//imitating the server side (.net, C#) duration formatting like:

    public static string Format(this TimeSpan interval)
    {
        string pattern;
        if (interval.Days > 0)          pattern = @"d\.h\:mm\:ss";
        else if (interval.Hours > 0)    pattern = @"h\:mm\:ss";
        else                            pattern = @"m\:ss";
        return string.Format("{0}", interval.ToString(pattern));
    }
