Javascript - Seconds to Time (hh:mm:ss,ms) -> sec2time(593.685038) becomes 00:09:53,685

sec2time.js

function sec2time(timeInSeconds) {
    var pad = function(num, size) { return ('000' + num).slice(size * -1); },
    time = parseFloat(timeInSeconds).toFixed(3),
    hours = Math.floor(time / 60 / 60),
    minutes = Math.floor(time / 60) % 60,
    seconds = Math.floor(time - minutes * 60),
    milliseconds = time.slice(-3);

    return pad(hours, 2) + ':' + pad(minutes, 2) + ':' + pad(seconds, 2) + ',' + pad(milliseconds, 3);
}

Working good, thanks.

Thank you!
