I use alarm() for a similar thing. just set up a signal handler that catches
SIGALRM, redraws the clock, and calls alarm(1) to update the clock once a
second. alarm(60) will update it once a minute.
then, at the beginning of the program, just call alarm(60) once and away
you go. if you ever need to turn off the clock update, just do alarm(0).
pretty simple.
