Convert seconds to HH-MM-SS with JavaScript?

Question

How can I convert seconds to an HH-MM-SS string using JavaScript?

Answer 1

You can also use below code:

int ss = nDur%60;
nDur   = nDur/60;
int mm = nDur%60;
int hh = nDur/60;

Answer 2

var  timeInSec = "661"; //even it can be string

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

alert("5678".toHHMMSS());   // "01:34:38"
console.log(timeInSec.toHHMMSS());   //"00:11:01"

we can make this function lot shorter and crisp but that decreases the readability, so we will write it as simple as possible and as stable as possible.

Answer 3

below is the given code which will convert seconds into hh-mm-ss format:

var measuredTime = new Date(null);
measuredTime.setSeconds(4995); // specify value of SECONDS
var MHSTime = measuredTime.toISOString().substr(11, 8);

Answer 4

I know this is kinda old, but...

ES2015:

var toHHMMSS = (secs) => {
    var sec_num = parseInt(secs, 10)
    var hours   = Math.floor(sec_num / 3600)
    var minutes = Math.floor(sec_num / 60) % 60
    var seconds = sec_num % 60

    return [hours,minutes,seconds]
        .map(v => v < 10 ? "0" + v : v)
        .filter((v,i) => v !== "00" || i > 0)
        .join(":")
}

It will output:

toHHMMSS(129600) // 36:00:00
toHHMMSS(13545) // 03:45:45
toHHMMSS(180) // 03:00
toHHMMSS(18) // 00:18

Answer 5

For the special case of HH:MM:SS.MS (eq: "00:04:33.637") as used by FFMPEG to specify milliseconds.

[-][HH:]MM:SS[.m...]

HH expresses the number of hours, MM the number of minutes for a maximum of 2 digits, and SS the number of seconds for a maximum of 2 digits. The m at the end expresses decimal value for SS.

/* HH:MM:SS.MS to (FLOAT)seconds ---------------*/
function timerToSec(timer){
   let vtimer = timer.split(":")
   let vhours = +vtimer[0]
   let vminutes = +vtimer[1]
   let vseconds = parseFloat(vtimer[2])
   return vhours * 3600 + vminutes * 60 + vseconds
}

/* Seconds to (STRING)HH:MM:SS.MS --------------*/
function secToTimer(sec){
  let o = new Date(0)
  let p =  new Date(sec*1000)  
  return new Date(p.getTime()-o.getTime())
    .toISOString()
    .split("T")[1]
    .split("Z")[0]
}

/* Example: 7hours, 4 minutes, 33 seconds and 637 milliseconds */
const t = "07:04:33.637"
console.log(
  t + " => " +
  timerToSec(t) +
  "s"
)

/* Test: 25473 seconds and 637 milliseconds */
const s = 25473.637 // "25473.637"
console.log(
  s + "s => " + 
  secToTimer(s)
)

Example usage, a milliseconds transport timer:

/* Seconds to (STRING)HH:MM:SS.MS --------------*/
function secToTimer(sec){
  let o = new Date(0)
  let p =  new Date(sec*1000)  
  return new Date(p.getTime()-o.getTime())
    .toISOString()
    .split("T")[1]
    .split("Z")[0]
}

let job, origin = new Date().getTime()
const timer = () => {
  job = requestAnimationFrame(timer)
  OUT.textContent = secToTimer((new Date().getTime() - origin) / 1000)
}

requestAnimationFrame(timer)

span {font-size:4rem}

<span id="OUT"></span>
<br>
<button onclick="origin = new Date().getTime()">RESET</button>
<button onclick="requestAnimationFrame(timer)">RESTART</button>
<button onclick="cancelAnimationFrame(job)">STOP</button>

Example usage, binded to a media element

/* Seconds to (STRING)HH:MM:SS.MS --------------*/
function secToTimer(sec){
  let o = new Date(0)
  let p =  new Date(sec*1000)  
  return new Date(p.getTime()-o.getTime())
    .toISOString()
    .split("T")[1]
    .split("Z")[0]
}

VIDEO.addEventListener("timeupdate", function(e){
  OUT.textContent = secToTimer(e.target.currentTime)
}, false)

span {font-size:4rem}

<span id="OUT"></span><br>
<video id="VIDEO" width="400" controls autoplay>

Outside the question, those functions written in php:

<?php 
/* HH:MM:SS to (FLOAT)seconds ------------------*/
function timerToSec($timer){
  $vtimer = explode(":",$timer);
  $vhours = (int)$vtimer[0];
  $vminutes = (int)$vtimer[1];
  $vseconds = (float)$vtimer[2];
  return $vhours * 3600 + $vminutes * 60 + $vseconds;
}
/* Seconds to (STRING)HH:MM:SS -----------------*/
function secToTimer($sec){
  return explode(" ", date("H:i:s", $sec))[0];  
}

var time2 = date2.getTime();
var totalMilisec = time2 - time1;
