Not clear for what purpose you need a "timer."  I just noticed one reply that
used a "busy-wait" (or "spin busy) loop to delay for a specified time.

If you just need a time-of-day resolution, you can get 1/60 second increments
using the times(2) routine as I posted a month or so ago re: my version of the
gettimeofday(2); actually the resolution is platform dependent ... see ``HZ''
in /usr/include/sys/param.h for the value on YOUR system (it's 60 on the 3B1).
