<?php  
$user1 = mysql_query("SELECT * FROM `users` WHERE `id`='$user->id'");
while($user = mysql_fetch_object($user1)){
   $data2 = mysql_query("SELECT *,UNIX_TIMESTAMP(`start`) AS `start`,0 FROM `users` WHERE `id`='$user->id'");
   $data1 = mysql_fetch_object($data2);
   $date = $user->howlong;
   $timedif1 = $data1->start-3600+$date-time();
   if($data1->start + $date > time()){
       list($h,$min,$sec)=explode(":",date("H:i:s",$timedif1));
       $countdown = $data1->start+$date-time();
   }
}
?>

Sen bitirmek için <?php echo $countdown ?> zaman var!
