Article not using extended date feature

[GoogleCodeExporter]

All dates are served in English, even thought the main language is German, 
Spanish, etc.
Adding    
setlocale(LC_ALL,"es_ES@euro","es_ES","esp"); 
not solves the problem because it works with strftime

Example:
echo date('l jS \of F Y h:i:s A'); English
echo strftime("%A, %B %d", time()); uses setlocale defined language
