[TYPO3-german] tt_news: correct date-format, but "days" instead of "Tage"

[E.Hermanns]

Hi List!

Didn't find a solution here for my tt_news-problem.

Installation: t3 dummy-3.8.1
tt_news 2.2.4
templaVoila

some snippets of my setup:
#------------------
config.language = de
config.locale_all = de_DE.utf8 at euro
config.metaCharset = utf-8
config.sys_language_uid = 1
....
plugin.tt_news.displayList.date_stdWrap.strftime = %A den %d %B %Y
#-------------------

tt_news "LIST" and SINGLE pages display dates like this:

"Samstag den 14 Januar 2006 Alter: 25 days"

How can i manage to get "Tage" instead of "days"?

Didnt find any hint in object-browser or EXT-manager setup for tt_news.
Any help is very much apreciated.
