Comment(by natethelen):

 Here is the change I made which cleaned up the problem.  I replaced:

     while ( $timestamp < time() + 1 )
         $timestamp += $interval;

 with:

     $now = time();

     if($timestamp >= $now)
         $timestamp = $now + $interval;
     else
         $timestamp = $now + ($interval - (($now - $timestamp) %
 $interval));

 This keeps the $timestamp in line with the difference from time() just
 like incrementing does, but without having to loop
