Convert seconds to HH-MM-SS with JavaScript?

Question

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

Answer 1

I ran into the case some have mentioned where the number of seconds is more than a day. Here's an adapted version of @Harish Anchu's top-rated answer that accounts for longer periods of time:

function secondsToTime(seconds) {
  const arr = new Date(seconds * 1000).toISOString().substr(11, 8).split(':');

  const days = Math.floor(seconds / 86400);
  arr[0] = parseInt(arr[0], 10) + days * 24;

  return arr.join(':');
}

Example:

secondsToTime(101596) // outputs '28:13:16' as opposed to '04:13:16'
