+ * 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.
