Yes, but the advantage of a nonnormalized tv_nsec field is that it can
be used with "legacy" structures which have "seconds since the epoch" in
the tv_sec field.

On the other hand, this may break existing applications which aren't
aware that the number in tv_nsec can exceed 1000000000, so those might
display strange timestamps. ;-)
