[TYPO3-mvc] Issues with DateTime objects and PHP 5.2.14 - always return present day

[Franz Koch]

Hey folks,

I need some help before going totally nuts. I've just installed a 
extbase (current GIT version) based extension on a live server running 
PHP 5.2.14 and have serious issues with DateTime objects.

For what reason ever all DateTime objects have the date of the present 
day and not the value stored in DB and I have no clue why. Anybody ever 
came across such a curiosity?
I try to get a update to PHP 5.3.x by the admins, but that might not be 
possible.

Any ideas?
