I have some information from the server returning after recording a video from another source, and I am having trouble finding the duration of that video. I tried calculating from StartTime, EndTime & ProcessingTime but the result is still not correct like I open 1 video from Player. Please see Data and formula below.

  <published>true</published>
  <start_time>1648193086010</start_time>
  <end_time>1648193354234</end_time>

</recording>

And here is my Code:

function DURATION(duration) {

const length = moment.duration(duration);h


const hour = length.hours(); 
const minute = length.minutes(); 
const second = length.seconds(); 

return hour + ':' + minute + ':' + second;

}

Result is 03:42
