[TYPO3-mvc] TYPO3 (TSFE) uses config.locale_all, fluid does not

[Steffen Ritter]

Hey folks,
I currently stumbled over strange behaviour:
My Dates I'm rendering with "format.date" write: 27. July 2010
Rendering the same timestamp via TS results to 27. Juli 2010.

So why could it be the case, that fluid does not take care of the 
settings in config.locale all?
