The POSIX.1 draft spec for utimensat() says that if a times[n].tv_nsec
field is UTIME_OMIT or UTIME_NOW, then the value in the corresponding
tv_sec field is ignored. However the current Linux implementation
requires the tv_sec value to be zero (or the EINVAL error results).
This requirement should be removed.
