How to convert time milliseconds to hours, min, sec format in JavaScript?

Question

I have the time as milliseconds, but I want the time after conversion like 00:00:00.

Ex: In milliseconds=86400000. I want how many hours in that millise

Answer 1

my solution

var sunriseMills = 1517573074000;         // sunrise in NewYork on Feb 3, 2018  - UTC time
var offsetCityMills = -5 * 3600 * 1000;   // NewYork delay to UTC 
var offsetDeviceMills =  new Date().getTimezoneOffset() * 60 * 1000 ;  // eg. I live in Romania (UTC+2) >> getTimezoneOffset() = 120

var textTime = new Date(sunriseMills + offsetCityMills + offsetDeviceMills) 
    .toLocaleTimeString('en-US', { hour: 'numeric', minute: 'numeric' });

textTime will become '7.04 AM'

Answer 2

I had the same problem, this is what I ended up doing:

function parseMillisecondsIntoReadableTime(milliseconds){
  //Get hours from milliseconds
  var hours = milliseconds / (1000*60*60);
  var absoluteHours = Math.floor(hours);
  var h = absoluteHours > 9 ? absoluteHours : '0' + absoluteHours;

  //Get remainder from hours and convert to minutes
  var minutes = (hours - absoluteHours) * 60;
  var absoluteMinutes = Math.floor(minutes);
  var m = absoluteMinutes > 9 ? absoluteMinutes : '0' +  absoluteMinutes;

  //Get remainder from minutes and convert to seconds
  var seconds = (minutes - absoluteMinutes) * 60;
  var absoluteSeconds = Math.floor(seconds);
  var s = absoluteSeconds > 9 ? absoluteSeconds : '0' + absoluteSeconds;


  return h + ':' + m + ':' + s;
}


var time = parseMillisecondsIntoReadableTime(86400000);

alert(time);

Answer 3

How about doing this by creating a function in javascript as shown below:

function msToTime(duration) {
  var milliseconds = parseInt((duration % 1000) / 100),
    seconds = Math.floor((duration / 1000) % 60),
    minutes = Math.floor((duration / (1000 * 60)) % 60),
    hours = Math.floor((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 + "." + milliseconds;
}
console.log(msToTime(300000))

Answer 4

Here is my solution

let h,m,s;
h = Math.floor(timeInMiliseconds/1000/60/60);
m = Math.floor((timeInMiliseconds/1000/60/60 - h)*60);
s = Math.floor(((timeInMiliseconds/1000/60/60 - h)*60 - m)*60);

// to get time format 00:00:00

s < 10 ? s = `0${s}`: s = `${s}`
m < 10 ? m = `0${m}`: m = `${m}`
h < 10 ? h = `0${h}`: h = `${h}`


console.log(`${s}:${m}:${h}`);
