Answer 1

Personally, going off other peoples answers I made my own parser. Works with days, hours, minutes and seconds. And should be easy to expand to weeks/months etc. It works with deserialisation to c# as well

function secondsToTimeInterval($seconds) {
    $t = round($seconds);
    $days = floor($t/86400);
    $day_sec = $days*86400;
    $hours = floor( ($t-$day_sec) / (60 * 60) );
    $hour_sec = $hours*3600;
    $minutes = floor((($t-$day_sec)-$hour_sec)/60);
    $min_sec = $minutes*60;
    $sec = (($t-$day_sec)-$hour_sec)-$min_sec;
    return sprintf('%02d:%02d:%02d:%02d', $days, $hours, $minutes, $sec);
}
