I have already send a previus bug report.
ID: 9921.

The Source is :

<?php 
   $fhandle = opendir("."); 

   while (false!=($file = readdir($fhandle))) 
   { 
      if ($file != "." && $file != "..") 
      { 
if (!(is_dir($file))) 
{ 
      $fdata = filemtime($file); 
      $fdata = date("d/m/Y",$fdata); 
      $fsize = filesize($file); 
     
              printf("%s %s %dn", $file, $fdata, $fsize); 

} 

clearstatcache(); 
closedir($fhandle); 
      } 
   } 
?> 


The Output for every file (no matter filesize or file date) is :


<filename> 01/01/1970 0


---------------------

I think i has something to do with the Y2K bug.
Perl had the same bug.
