JavaScript seconds to time string with format hh:mm:ss
JavascriptDateTimeDate FormatTime FormatJavascript Problem Overview
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?
Javascript Solutions
Solution 1 - 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());
Solution 2 - Javascript
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().substr(11, 8);
console.log(timeString)
Solution 3 - Javascript
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)
Solution 4 - Javascript
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'.
Solution 5 - Javascript
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;
}
Solution 6 - Javascript
Here's my take on it:
function formatTime(seconds) {
const h = Math.floor(seconds / 3600);
const m = Math.floor((seconds % 3600) / 60);
const s = Math.round(seconds % 60);
return [
h,
m > 9 ? m : (h ? '0' + m : m || '0'),
s > 9 ? s : '0' + s
].filter(Boolean).join(':');
}
Expected results:
const expect = require('expect');
expect(formatTime(0)).toEqual('0:00');
expect(formatTime(1)).toEqual('0:01');
expect(formatTime(599)).toEqual('9:59');
expect(formatTime(600)).toEqual('10:00');
expect(formatTime(3600)).toEqual('1:00:00');
expect(formatTime(360009)).toEqual('100:00:09');
expect(formatTime(0.2)).toEqual('0:00');
Solution 7 - Javascript
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;
}
Solution 8 - Javascript
function formatTime(seconds) {
return [
parseInt(seconds / 60 / 60),
parseInt(seconds / 60 % 60),
parseInt(seconds % 60)
]
.join(":")
.replace(/\b(\d)\b/g, "0$1")
}
Solution 9 - Javascript
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;
}
Solution 10 - Javascript
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.
Solution 11 - Javascript
It's pretty easy,
function toTimeString(seconds) {
return (new Date(seconds * 1000)).toUTCString().match(/(\d\d:\d\d:\d\d)/)[0];
}
Solution 12 - Javascript
new Date().toString().split(" ")[4];
result 15:08:03
Solution 13 - Javascript
Easiest way to do it.
new Date(sec * 1000).toISOString().substr(11, 8)
Solution 14 - Javascript
s2t=function (t){
return parseInt(t/86400)+'d '+(new Date(t%86400*1000)).toUTCString().replace(/.*(\d{2}):(\d{2}):(\d{2}).*/, "$1h $2m $3s");
}
s2t(123456);
result:
1d 10h 17m 36s
Solution 15 - Javascript
I loved Powtac's answer, but I wanted to use it in angular.js, so I created a filter using his code.
.filter('HHMMSS', ['$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
Solution 16 - Javascript
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"
Solution 17 - Javascript
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; }
Solution 18 - Javascript
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;
}
Solution 19 - Javascript
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"
Solution 20 - Javascript
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
Solution 21 - 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");
}
Solution 22 - Javascript
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))
};
Solution 23 - Javascript
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

const secondsToTime = (seconds, locale) => {
const date = new Date(0);

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);
}
Solution 27 - Javascript
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

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"

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);
}

I'd upvote artem's answer, but I am a new poster. I did expand on his solution, though not what the OP asked for as follows
t=(new Date()).toString().split(" ");
timestring = (t[2]+t[1]+' <b>'+t[4]+'</b> '+t[6][1]+t[7][0]+t[8][0]);
To get
04Oct 16:31:28 PDT
This works for me...
But if you are starting with just a time quantity, I use two functions; one to format and pad, and one to calculate:
function sec2hms(timect){
if(timect=== undefined||timect==0||timect === null){return ''};
//timect is seconds, NOT milliseconds
var se=timect % 60; //the remainder after div by 60
timect = Math.floor(timect/60);
var mi=timect % 60; //the remainder after div by 60
timect = Math.floor(timect/60);
var hr = timect % 24; //the remainder after div by 24
var dy = Math.floor(timect/24);
return padify (se, mi, hr, dy);
}
function padify (se, mi, hr, dy){
hr = hr<10?"0"+hr:hr;
mi = mi<10?"0"+mi:mi;
se = se<10?"0"+se:se;
dy = dy>0?dy+"d ":"";
return dy+hr+":"+mi+":"+se;
}

If you know the number of seconds you have, this will work. It also uses the native Date() object.
function formattime(numberofseconds){
var zero = '0', hours, minutes, seconds, time;
time = new Date(0, 0, 0, 0, 0, numberofseconds, 0);
hh = time.getHours();
mm = time.getMinutes();
ss = time.getSeconds()
// Pad zero values to 00
hh = (zero+hh).slice(-2);
mm = (zero+mm).slice(-2);
ss = (zero+ss).slice(-2);
time = hh + ':' + mm + ':' + ss;
return time;
}
Solution 36 - Javascript
Milliseconds to duration, the simple way:
// To have leading zero digits in strings.
function pad(num, size) {
var s = num + "";
while (s.length < size) s = "0" + s;
return s;
}
// ms to time/duration
msToDuration = function(ms){
var seconds = ms / 1000;
var hh = Math.floor(seconds / 3600),
mm = Math.floor(seconds / 60) % 60,
ss = Math.floor(seconds) % 60,
mss = ms % 1000;
return pad(hh,2)+':'+pad(mm,2)+':'+pad(ss,2)+'.'+pad(mss,3);
}
It converts 327577 to 00:05:27.577.
UPDATE
Another way for different scenario:
toHHMMSS = function (n) {
var sep = ':',
n = parseFloat(n),
sss = parseInt((n % 1)*1000),
hh = parseInt(n / 3600);
n %= 3600;

Non-prototype version of toHHMMSS:
function toHHMMSS(seconds) {
var sec_num = parseInt(seconds);
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;}
var time = hours+':'+minutes+':'+seconds;
return time;
}

Here is my vision of solution. You can try my snippet below.
function secToHHMM(sec) {
var d = new Date();
d.setHours(0);
d.setMinutes(0);
d.setSeconds(0);
d = new Date(d.getTime() + sec*1000);
return d.toLocaleString('en-GB').split(' ')[1];
};
alert( 'One hour: ' + secToHHMM(60*60) ); // '01:00:00'
alert( 'One hour five minutes: ' + secToHHMM(60*60 + 5*60) ); // '01:05:00'
alert( 'One hour five minutes 23 seconds: ' + secToHHMM(60*60 + 5*60 + 23) ); // '01:05:23'

This version of the accepted answer makes it a bit prettier if you are dealing with video lengths for example:
1:37:40 (1 hour / 37 minutes / 40 seconds)
1:00 (1 minute)
2:20 (2 minutes and 20 seconds)
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);
var hourSeparator = ':';
var minuteSeparator = ':';
if(hours == 0){hours = '';hourSeparator = '';}
if (minutes < 10 && hours != 0) {minutes = "0"+minutes;}
if (seconds < 10) {seconds = "0"+seconds;}
var time = hours+hourSeparator+minutes+minuteSeparator+seconds;
return time;
}

//secondsToTime();
var t = wachttijd_sec; // your seconds
var hour = Math.floor(t/3600);
if(hour < 10){
hour = '0'+hour;
}
var time = hour+':'+('0'+Math.floor(t/60)%60).slice(-2)+':'+('0' + t % 60).slice(-2);
//would output: 00:00:00 > +100:00:00
keeps counten down even if more then 24 hours

You can use Momement.js with 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

Here is an es6 Version of it:
export const parseTime = (time) => { // send time in seconds
// eslint-disable-next-line
let hours = parseInt(time / 60 / 60), mins = Math.abs(parseInt(time / 60) - (hours * 60)), seconds = Math.round(time % 60);
return isNaN(hours) || isNaN(mins) || isNaN(seconds) ? `00:00:00` : `${hours > 9 ? Math.max(hours, 0) : '0' + Math.max(hours, 0)}:${mins > 9 ? Math.max(mins, 0) : '0' + Math.max(0, mins)}:${seconds > 9 ? Math.max(0, seconds) : '0' + Math.max(0, seconds)}`;}

Here's a one-liner updated for 2019:
//your date
var someDate = new Date("Wed Jun 26 2019 09:38:02 GMT+0100")
var result = `${String(someDate.getHours()).padStart(2,"0")}:${String(someDate.getMinutes()).padStart(2,"0")}:${String(someDate.getSeconds()).padStart(2,"0")}`
//result will be "09:38:02"

I saw that everybody's posting their takes on the problem despite the fact that few top answers already include all the necessary info to tailor for the specific use case.
And since I want to be hip as well - here's my unnecessary and a bit cumbersome solution, which is:
a) Readable (I hope!)
b) Easily customizable
c) Doesn't print any zeroes
drum roll
function durationToDDHHMMSSMS(durms) {
if (!durms) return "??";
var HHMMSSMS = new Date(durms).toISOString().substr(11, 12);
if (!HHMMSSMS) return "??";
var HHMMSS = HHMMSSMS.split(".")[0];
if (!HHMMSS) return "??";
var MS = parseInt(HHMMSSMS.split(".")[1],10);
var split = HHMMSS.split(":");
var SS = parseInt(split[2],10);
var MM = parseInt(split[1],10);
var HH = parseInt(split[0],10);
var DD = Math.floor(durms/(1000*60*60*24));
var string = "";
if (DD) string += ` ${DD}d`;
if (HH) string += ` ${HH}h`;
if (MM) string += ` ${MM}m`;
if (SS) string += ` ${SS}s`;
if (MS) string += ` ${MS}ms`;
return string;
},
Note that this code uses ES6 template strings, I'm sure that such a smarty-pants as you are will have no difficulties replacing them with regular strings if required.
Solution 46 - Javascript
I dislike adding properties to standard datatypes in JavaScript, so I would recommend something like this:
/**
* Format a duration in seconds to a human readable format using the notion
* "h+:mm:ss", e.g. "4:40:78". Negative durations are preceeded by "-".
*
* @param t Duration in seconds
* @return The formatted duration string
*/
var readableDuration = (function() {
// Each unit is an object with a suffix s and divisor d
var units = [
{s: '', d: 1}, // Seconds
{s: ':', d: 60}, // Minutes
{s: ':', d: 60}, // Hours
];
// Closure function
return function(t) {
t = parseInt(t); // In order to use modulus
var trunc, n = Math.abs(t), i, out = []; // out: list of strings to concat
for (i = 0; i < units.length; i++) {
n = Math.floor(n / units[i].d); // Total number of this unit
// Truncate e.g. 26h to 2h using modulus with next unit divisor
if (i+1 < units.length) // Tweak substr with two digits
trunc = ('00'+ n % units[i+1].d).substr(-2, 2); // …if not final unit
else
trunc = n;
out.unshift(''+ trunc + units[i].s); // Output
}
(t < 0) ? out.unshift('-') : null; // Handle negative durations
return out.join('');
};
})();
Usage:
var str = readableDuration(3808); // "1:03:28"
I also created a more generally usable version. The main difference is that it accepts milliseconds (which is kind of the standard time unit in JS) and the output format uses spaces instead.
