Cross-referencing all the standards properly is a bit of a pain, and it should be enough to put that info in the documentation as I did in my recent time.texi patch. 2002-03-13 Paul Eggert <eggert@twinsun.com> * manual/time.texi (Formatting Calendar Time): ISO C99 also specifies the E and O modifiers. %P is a GNU extension, and is not in ISO C99. Mention that %r is equivalent to %I:%M:%S %p in the POSIX locale. %T is also in ISO C99. The RFC 822 example is not valid in arbitrary locales. Reword the POSIX.2 wording slightly, to make it a bit clearer that POSIX.2 formats are also supported by later POSIX versions. If a format was introduced in ISO C99 it is also required by POSIX.1-2001.
