Changing Date format in concrete 5.6.2.1

Permalink
Hi all,

since a couple of days I try to change the date-format in Concrete5 from e.g. "29. December 2013" to "29. Dezember 2013", but I don`t get it. I alreday put these lines in site.php:


define('DATE_APP_GENERIC_MDY', 'j.n.Y');
define('DATE_APP_GENERIC_MDYT_FULL', 'j.n.Y H:i:s');
define('DATE_APP_GENERIC_MDYT', 'j.n.Y H:i:s');
define('DATE_APP_DATE_PICKER', 'dd.mm.yy');
define('DATE_FORM_HELPER_FORMAT_HOUR', '24');
@setlocale(LC_ALL, 'de_DE');

I changed in \c5\concrete\config\localization.php

all the en_US-entries to de_DE-entries, no success.....
Could anybod give me a hint what to do please?
