[TYPO3-ttnews] tx_news - Date doesent work

[Bader Paul]

The following fluid code in the List/Item.html

<f:format.date format="l, d. F Y">{newsItem.datetime}</f:format.date>

gives me a English Format as

Thursday, 08. December 2011 back.


In my Typoscript Setup is set
config.sys_language_uid = 0
config.language = de
config.locale_all = de_DE.utf-8

and in
/etc/apache2/envvars:

## The locale used by some modules like mod_dav
export LANG="de_DE.utf8"
export LC_ALL="de_DE.utf8"


Have anywhere an idea whats wrong or what can i do that i get an German 
Format like

Donnerstag, 08. Dezember 2011 back.
