If you confirm, I will send a patch.
Yes, it is a known problem, turned up by some the posix timers tests. I suppose it is too much to ask, but it would be nice if do_sys_settimeofday() took a timespec instead of a timeval. Of course this changes the interface for all the archs, but it would allow the clock_settimeofday to send in the nsec value.
