I had to look up stime(). That's a System V R4 method that I have never
used.  It sure isn't part of POSIX.

The POSIX way is clock_settime(CLOCK_REALTIME,...).

The Classic API way is rtems_clock_set().

cpukit/libmisc/shell/main_date.c has a simple example of using

Interesting that there has never been a mention of stime() before.
