FWIW, clock_settime already disallows negative times due to the
existing check in the previous two lines:

	if (ats->tv_nsec < 0 || ats->tv_nsec >= 1000000000 ||
	    ats->tv_sec < 0)
		return (EINVAL);

I would probably lean towards not disallowing negative times as I
said in one of my earlier replies, but given we have that blanket
check already in place, the current patch doesn't seem to make
things much worse.
