Here's the one I wrote as a result of this thread.  It does work,
feel free to finger me (kaleb at nutmeg.jpl.nasa.gov) if you doubt my
word.

It may not be the epitome of efficiency, so I'll gladly take tips
on making it better.

#include <time.h>
#include <sys/types.h>
#include <sys/time.h>
#include <fcntl.h>

main ()

{

    int     planfile;
    int     number = 0;
    time_t  tim;
    char    *planmessage = "You are the %d%s person to finger me\nat the tone, the time will be %s\n"; 
    char    target[256];
    char    *consmessage = "you have been fingered\n";
    char    *index2;

    for (;;) {

        planfile = open (".plan", O_WRONLY );

        time (&tim);
        switch (number % 10) {
            case 1: index2 = "st"; break;
            case 2: index2 = "nd"; break;
            case 3: index2 = "rd"; break;
            default: index2 = "th"; break;
        }
        sprintf (target,planmessage, number++, index2, asctime (localtime (&tim)));
        write (planfile, target, strlen (target));

        write (1, consmessage, strlen (consmessage));
        close (planfile);

        sleep (1);

    }
}
