function secondsToHms(d) {
d = Number(d);
var h = Math.floor(d / 3600);
var m = Math.floor(d % 3600 / 60);
var s = Math.floor(d % 3600 % 60);
return ('0' + h).slice(-2) + ":" + ('0' + m).slice(-2) + ":" + ('0' + s).slice(-2);
}
document.writeln('secondsToHms(10) = ' + secondsToHms(10) + '<br>');
document.writeln('secondsToHms(30) = ' + secondsToHms(30) + '<br>');
document.writeln('secondsToHms(60) = ' + secondsToHms(60) + '<br>');
document.writeln('secondsToHms(100) = ' + secondsToHms(100) + '<br>');
document.writeln('secondsToHms(119) = ' + secondsToHms(119) + '<br>');
document.writeln('secondsToHms(500) = ' + secondsToHms(500) + '<br>');
