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

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 );
