New Comment:
Which would be why it isn't a bug. Start with a timestamp around noon
to avoid DST issues like this.
You probably also want to use something like this instead:
$db = new DateTime('2008-12-31');
$de = new DateTime('2009-12-31');
$di = DateInterval::createFromDateString('Sunday next week');
$dp = new DatePeriod($db, $di, $de, DatePeriod::EXCLUDE_START_DATE);
foreach($dp as $dt) {
echo $dt->format("F jS\n") . "<br>\n";
}
This would give you the date of each Sunday in 2009, except the first
one (because of the EXCLUDE_START_DATE) option.

Description:
------------
On Sept 11, 2009 I was calculating the date for each successive sunday
and used the code below, but after Nov 1, 2009, the day changes to
Saturday. Is this a bug? It appears to be related to daylight savings
time.
Reproduce code:
---------------
<?php
for ($w= 5; $w < 15; $w++) {
echo date('Y-m-d, D, z', (strtotime('sunday') + $w*7*24*60*60)) .
"<br>";
}
?>
Expected result:
----------------
Return the date of each sunday starting 5 weeks from this coming
sunday.
Actual result:
--------------
