javascriptfunction plural($num) { if ($num !=1) return s;}

function getRelativeTime($date) { $diff=time() - strtotime($date); if ($diff <60) return $diff . second + plural($diff) + ago; $diff=round($diff / 60); if ($diff < 60) return $diff . minute + plural($diff) + ago; $diff=round($diff / 60); if ($diff < 24) return $diff . hour + plural($diff) + ago; $diff=round($diff / 24); if ($diff < 30) return $diff . day + plural($diff) + ago; $diff=round($diff / 30); if ($diff < 12) return $diff . month + plural($diff) + ago; return $diff . year + plural($diff) + ago;}

function plural($num) { if ($num != 1) return "s"; } function getRelativeTime($date) { $diff = time() - strtotime($date); if ($diff<60) return $diff . " second" . plural($diff) .
