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?
This question is related to
javascript
date
time
date-format
time-format
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;
}
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"
Here is a fairly simple solution that rounds to the nearest second!
var returnElapsedTime = function(epoch) {_x000D_
//We are assuming that the epoch is in seconds_x000D_
var hours = epoch / 3600,_x000D_
minutes = (hours % 1) * 60,_x000D_
seconds = (minutes % 1) * 60;_x000D_
return Math.floor(hours) + ":" + Math.floor(minutes) + ":" + Math.round(seconds);_x000D_
}
_x000D_
You can use Momement.js with moment-duration-format plugin:
var seconds = 3820;_x000D_
var duration = moment.duration(seconds, 'seconds');_x000D_
var formatted = duration.format("hh:mm:ss");_x000D_
console.log(formatted); // 01:03:40

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');
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
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");
}
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);_x000D_
date.setSeconds(45); // specify value for SECONDS here_x000D_
var timeString = date.toISOString().substr(11, 8);_x000D_
console.log(timeString)
_x000D_
function secondsToTime(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);
if(hours >= 12)
{
var m= 'pm' ;
}
else
{
var m='am'
}
if(hours-12 >0)
{
var hrs = hours-12;
}
else if(hours-12 <0)
{
var hrs = hours;
}
var obj = {
"h": hrs,
"m": minutes,
"s": seconds,
"a":m
};
return obj;
}
var d = new Date();
var n = d.getHours();
var hms = d.getHours()+':'+d.getMinutes()+':'+d.getSeconds(); // your input string
var a = hms.split(':'); // split it at the colons
// minutes are worth 60 seconds. Hours are worth 60 minutes.
var seconds = (+a[0]) * 60 * 60 + (+a[1]) * 60 + (+a[2]);
console.log(seconds);
console.log(secondsToTime(seconds))
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))
};
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.
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'
const secondsToTime = (seconds, locale) => {_x000D_
const date = new Date(0);_x000D_
date.setHours(0, 0, seconds, 0);_x000D_
return date.toLocaleTimeString(locale);_x000D_
}_x000D_
console.log(secondsToTime(3610, "en"));
_x000D_
where the locale parameter ("en", "de", etc.) is optional
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 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.)
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'
.
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;
}
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"
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;
}
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
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);

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+":";
}

time = seconds+"s";
}
else {
time += (seconds < 10) ? "0"+seconds : String(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 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
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>';

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
/**

* 0:50
* 2:00
* 12:00
* 1:00:24
* 10:00:00
*/
export default function formatTimeHIS (seconds, { short = false } = {}) {
const pad = num => num < 10 ? `0${num}` : num
const H = pad(Math.floor(seconds / 3600))
const i = pad(Math.floor(seconds % 3600 / 60))
const s = pad(seconds % 60)
if (short) {
let result = ''
if (H > 0) result += `${+H}:`
result += `${H > 0 ? i : +i}:${s}`
return result
} else {
return `${H}:${i}:${s}`
}
}
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");_x000D_
console.log(myDate)
_x000D_
It's pretty easy,
function toTimeString(seconds) {
return (new Date(seconds * 1000)).toUTCString().match(/(\d\d:\d\d:\d\d)/)[0];
}
Here is my vision of solution. You can try my snippet below.
function secToHHMM(sec) {_x000D_
var d = new Date();_x000D_
d.setHours(0);_x000D_
d.setMinutes(0);_x000D_
d.setSeconds(0);_x000D_
d = new Date(d.getTime() + sec*1000);_x000D_
return d.toLocaleString('en-GB').split(' ')[1];_x000D_
};_x000D_
_x000D_
alert( 'One hour: ' + secToHHMM(60*60) ); // '01:00:00'_x000D_
alert( 'One hour five minutes: ' + secToHHMM(60*60 + 5*60) ); // '01:05:00'_x000D_
alert( 'One hour five minutes 23 seconds: ' + secToHHMM(60*60 + 5*60 + 23) ); // '01:05:23'
_x000D_
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;
}
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;
}
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;
}
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;
}
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.
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

Easiest way to do it.
new Date(sec * 1000).toISOString().substr(11, 8)
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));
}
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;
var mm = parseInt(n / 60),
ss = parseInt(n % 60);
return pad(hh,2)+sep+pad(mm,2)+sep+pad(ss,2)+'.'+pad(sss,3);
function pad(num, size) {
var str = num + "";
while (str.length < size) str = "0" + str;
return str;
}
}
toHHMMSS(6315.077) // Return 01:45:15.077
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
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"
