Description:
------------
Currently it says:

    /*
     * We want the access time to be 1 week 
     * before the current access time.
     */

But 'cause of
$atime = $stat['atime'] + 604800;
It's not "before" but "after" the current acces time.

This means, change it to:

    /*
     * We want the access time to be 1 week 
     * after the current access time.
     */

The german translation has the same problem.

Expected result:
----------------
    /*
     * We want the access time to be 1 week 
     * after the current access time.
     */

Actual result:
--------------
    /*
     * We want the access time to be 1 week 
     * before the current access time.
     */
