Bug in pthread_cond_timedwait or we need an improvement?

pthread_cond_timedwait returns ETIMEDOUT instead of e.g. EINVAL when provided with "timespec *restrict abstime" whose tv_nsec part exceeds 999999999 (basically, it's more than 1 second). Furthermore, IMHO pthread_cond_timedwait should return ETIME instead of ETIMEDOUT (if we follow comments in: Anyway, if you want to avoid a few hours of debugging then make sure that your tv_nsec is correct in each timespec struct!
