+ 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.
