I have taken a look at your observed issue. The clock layout is  
handled via the i18n translation system underneath mate-screensaver. I  
presume that a POSIX locale is mapped to en_US.UTF-8 (though not  
sure), so the English translation scheme applies.

To make LC_TIME=POSIX and also LC_ALL=POSIX be interpreted correctly,  
you probably need to patch src/gs-lock-plug.c around line 304. [1]

My suggestion about this bug: I reduce it to wishlist, you start  
working on a patch and then the two of use try convincing upstream of  
accepting it.

Regards,
Mike
