/**
* Function to do a last minute fixup of the AM/PM stuff if the locale
* and gettext haven't done it right. Most English speaking countries
* except the USA use the 24 hour clock (UK, Australia etc). However
* since they are English nobody bothers to write a language
* translation (gettext) file. So the locale turns off the AM/PM, but
* gettext does not turn on the 24 hour clock. Leaving a mess.
*
* This routine checks if AM/PM are defined in the locale, if not it
* forces the use of the 24 hour clock.
*
* The function itself is a front end on strftime and takes exactly
* the same arguments.
*
* TODO: Actually remove the '%p' from the fixed up string so that
* there isn't a stray space.
