In subclause 18.104.22.168p7, the specifications for the strftime%c, %p, and %x conversion specifiers in the C locale conflict with the specifications in ISO/IEC 9945-2 for the POSIX locale. As the POSIX and C locales have always been intended to be compatible, we strongly suggest changing these specifications to match the pre-existing POSIX specifications.
In subclause 22.214.171.124, paragraph 7, page 345, change the definitions of %c, %p, and %x to:
%c equivalent to "%a %b %e %T %Y".
%p one of "AM" or "PM".
%x equivalent to "%m/%d/%y".
