From: re dot lewis at comcast dot net
Operating system: Linux
PHP version: 5.2.10
PHP Bug Type: Date/time related
Bug description: Incorrect dates returned with strtotime
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:
--------------
