At least, my system can return 1ns unit.
(It doesn't mean 1ns accuracy, of course.)

In following result, 4666 and 4667 are returned.

% ./ruby -ve '
t1 = Process.clock_gettime(Process::CLOCK_PROCESS_CPUTIME_ID, :nanoseconds)
while true
  t2 = Process.clock_gettime(Process::CLOCK_PROCESS_CPUTIME_ID, :nanoseconds)
  p t2-t1
  t1 = t2
end
