You can be assured of accessing the software clock if you call the C 
function gettimeofday().  Using it in RPG is not very easy since 
gettimeofday() required a pointer to a struct timeval.

You could also call time() and then convert the result to your locale with 
localtime().  Again, both use C structures that RPG doesn't have.  You 
could create a C module that does it though.  Here is some C sample code:

#include <stdio.h>
#include <time.h>

int
main ()
{
  time_t curtime;
  struct tm *date;

  curtime = time (NULL);
  date = localtime (&curtime);
  printf ("The date and time is: "%04d%02d%02d %02d:%02d:%02d\n",
          date->tm_year + 1900, date->tm_mon + 1, date->tm_mday,
          date->tm_hour, date->tm_min, date->tm_sec);
  return 0;
}
