Then I would suggest that you changed i18n:set_locale() somewhere in your code or you overloaded $lang['de_DE']['Date']['TIMEDIFFAGO'] or the language file is not loaded.
You can check your locale if you place "echo i18n::get_locale();" & "echo _t('Date.DAYS');" in e.g. your init method. It should return "de_DE" & "Tage".
