/* MAJOR TEST FUNCTIONALITY - READ THIS CAREFULLY
*
* STDLIB date handling is done in terms of seconds since the "epoch", which was
* 00:00 on 1st January, 1970. The Y2K significant functionality consists solely of the
* routines which manipulate the struct tm data structure.
*
* time_t mktime (struct tm *brokentime)
*
* struct tm * gmtime (const time_t *time)
* struct tm * localtime (const time_t *time)
*
* The mktime conversion is always using a GMT date, so we'll ignore the localtime function for Y2K
* purposes. We also know that gmtime and localtime use the same underlying conversion function,
* one applying the relevant GMT offset on the way in.
*
* Y2K is only concerned with dates, so we will always use 12:00:00 ("High Noon") as the time
* of day.
