If we want only hh:mm:ss, we can use a function like that:

//param: duration in milliseconds
MillisecondsToTime: function(duration) {
    var seconds = parseInt((duration/1000)%60)
        , minutes = parseInt((duration/(1000*60))%60)
        , hours = parseInt((duration/(1000*60*60))%24)
        , days  = parseInt(duration/(1000*60*60*24));

    var hoursDays = parseInt(days*24);
    hours += hoursDays;
    hours = (hours < 10) ? "0" + hours : hours;
    minutes = (minutes < 10) ? "0" + minutes : minutes;
    seconds = (seconds < 10) ? "0" + seconds : seconds;
    return hours + ":" + minutes + ":" + seconds;
}
