How can I convert milliseconds to “hhmmss” format using javascript?

Question

I am using javascript Date object trying to convert millisecond to how many hour, minute and second it is.

I have the currentTime in milliseconds

var         


        

Answer 1

Convert ms to hh:mm:ss

function millisecondsToHuman(ms) {
  const seconds = Math.floor((ms / 1000) % 60);
  const minutes = Math.floor((ms / 1000 / 60) % 60);
  const hours = Math.floor((ms  / 1000 / 3600 ) % 24)

  const humanized = [
    pad(hours.toString(), 2),
    pad(minutes.toString(), 2),
    pad(seconds.toString(), 2),
  ].join(':');

  return humanized;
}
=

Answer 2

var secDiff = timeDiff / 1000; //in s
var minDiff = timeDiff / 60 / 1000; //in minutes
var hDiff = timeDiff / 3600 / 1000; //in hours  

updated

function msToHMS( ms ) {
    // 1- Convert to seconds:
    var seconds = ms / 1000;
    // 2- Extract hours:
    var hours = parseInt( seconds / 3600 ); // 3,600 seconds in 1 hour
    seconds = seconds % 3600; // seconds remaining after extracting hours
    // 3- Extract minutes:
    var minutes = parseInt( seconds / 60 ); // 60 seconds in 1 minute
    // 4- Keep only seconds not extracted to minutes:
    seconds = seconds % 60;
    alert( hours+":"+minutes+":"+seconds);
}

var timespan = 2568370873; 
msToHMS( timespan );

Answer 3

var timediff = futureTime - currentTime
long seconds = (long) (timediff / 1000) % 60 ;
long minutes = (long) ((timediff / (1000*60)) % 60);
long hours   = (long) ((timediff / (1000*60*60)) % 24);
if(hours>0)
    time = hours+" hrs : "+minutes+" mins";
else if(minutes>0)
    time = minutes+" mins";
else if(seconds>0)
    time = seconds+" secs";

Answer 4

function msToHMS( duration ) {

     var milliseconds = parseInt((duration % 1000) / 100),
        seconds = parseInt((duration / 1000) % 60),
        minutes = parseInt((duration / (1000 * 60)) % 60),
        hours = parseInt((duration / (1000 * 60 * 60)) % 24);

      hours = (hours < 10) ? "0" + hours : hours;
      minutes = (minutes < 10) ? "0" + minutes : minutes;
      seconds = (seconds < 10) ? "0" + seconds : seconds;

      return hours + ":" + minutes + ":" + seconds ;
}

Answer 5

The difference in time is in milliseconds: Get time difference between two dates in seconds

to get the difference you have to use math.floor() http://www.w3schools.com/jsref/jsref_floor.asp

var secDiff = Math.floor(timeDiff / 1000); //in s
var minDiff = Math.floor(timeDiff / 60 / 1000); //in minutes
var hDiff = Math.floor(timeDiff / 3600 / 1000); //in hours

Answer 6

If you are confident that the period will always be less than a day you could use this one-liner:

new Date(timeDiff).toISOString().slice(11,19)   // HH:MM:SS

N.B. This will be wrong if timeDiff is greater than a day.
