Please run this code with 5.0.4 and tell me what you get:
?php
$date = strtotime('25 Oct');
var_dump(date('m/d/Y H:m:s', $date+(86400*6)));
var_dump(date('m/d/Y H:m:s', strtotime(+6 days, $date)));

Actually I realize 86400*6 should not be right as my code displays
below. It should give you back one hour short, however when I do add
86400*6 onto the day in PHP 5.1.X I am getting the exact 6 days out.
That would be a problem. Again PHP 5.0.4 handles this correctly.

Obviosly 6 days is not equal to 86400*6, exactly because of
daylight savings.
Change this line:
echo date('m/d/Y H:m:s', $date+(86400*6));
to
echo date('m/d/Y H:m:s', strtotime(+6 days, $date));

Description:
the newest 5.1.X version of PHP does not seem to work with day light
savings time. the Expected result was recieved from PHP 5.0.4
I am adding 6 days to Oct 25th to cross over daylight savings time on
Oct 30th. There should be 25 hours in Oct 30th.
Reproduce code:
---
$date = strtotime('25 Oct');
echo date('m/d/Y H:m:s', $date+(86400*6));
Expected result:
10/30/2005 23:10:00
Actual result:
--
10/31/2005 00:10:00

you get the expected result:
string(19) 10/30/2005 23:10:00 string(19) 10/31/2005 00:10:00
However in PHP 5.1.X I get:
string(19) 10/31/2005 00:10:00 string(19) 10/31/2005 00:10:00
Which is wrong.

This could be also a timezone issue.
What's your TZ ?

I have upgraded to the newest snap as you have requested and I am still
getting the same results. PHP 5.0.4 returns the correct time. PHP
5.1.X returns the wrong time. Could this be an operating system issue?
I am on Windows XP with Apache 2.
