[aklug] Nanosecond resolution for process timer?

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Okay, I'm posting this at 3 in the morning -- I hope I am still
communicating understandably...

So say you want to get the process time consumed by a function or a
small program. Is it possible to get that value in nanoseconds?
Everything I read online says best we can do is microseconds, but then
most everything I find online is years old, so I thought I would double
check...

I found clock_t times(struct tms *buf) from <sys/times.h>, which returns
the number of "clock times", but on my system the CLOCKS_PER_SEC value
is 1000000, so I think that means microseconds is still the best we can
do. (Aside, of course, from running process many times and averaging the
results...)
