We are happy to tell you that you just discovered Daylight Savings
Time. For more information see:

Instead of using mktime/date consider using gmmktime and gmdate which
do
not suffer from DST.

there is problem with mktime. it caclulates badly seconds in pedroids
27-28 march in some years like 2005. Possibly some other pedroids are
affected. this is just example to make bug search easier.
Reproduce code:
---------------
<?
$a1 = mktime(0,0,0,3,27,2005);
$a2 = mktime(0,0,0,3,28,2005);
$w = ($a2 - $a1) / 60 / 60 / 24;
echo $w;
echo "<br>\n";
$a1 = mktime(0,0,0,3,27,2006);
$a2 = mktime(0,0,0,3,28,2006);
$w = ($a2 - $a1) / 60 / 60 / 24;
echo $w;
?>
Expected result:
