One minor clarification - This is occurring in every version above 5.3.8.
After running git bisect, I've narrowed it down to this particular commit:
https://github.com/php/php-src/commit/7411ae09f5565b3f0dfbbfeb71c8f848fd38d6ca

My result is object(DateTime)#2 (3) { ["date"]=> string(19) "1970-01-01
00:00:05"
["timezone_type"]=> int(1) ["timezone"]=> string(6) "+00:00" }
My system is MAC 10.6.8 php 5.3.1

Description:
------------
When I create a DateTime object from a (any) timestamp and then add a DateInterval object to the
DateTime object, the time in the DateInterval object is added and one additional hour is also added.
I have not noticed this behavior in versions up to and including 5.3.8, only in newer 5.3 versions.
(I did not test in 5.4.)
Also the behavior is related to the default time zone, even though the created DateTime object is in
UTC. I have tested several timezones and it appears that all Europe/* and North American America/*
timezones are affected. The Australian timezones seem to be unaffected.
Information from phpinfo():
date
- date/time support => enabled
- "Olson" Timezone Database Version => 2012.3
- Timezone Database => internal
Test script:
---------------
date_default_timezone_set('Europe/Amsterdam');
$d1 = new DateTime('@0');
$d2 = clone($d1);
$d2->add(new DateInterval('PT5S'));
var_dump($d2);
Expected result:
----------------
object(DateTime)[2]
public 'date' => string '1970-01-01 00:00:05' (length=19)
public 'timezone_type' => int 1
public 'timezone' => string '+00:00' (length=6)
Actual result:
--------------
object(DateTime)[2]
public 'date' => string '1970-01-01 01:00:05' (length=19)
public 'timezone_type' => int 1
public 'timezone' => string '+00:00' (length=6)
