Are you sure of that?  I don't have the standard handy (it's non-free,
right?) but it seems that the Annex B states differently.  But that's
not the point anyway.  My concern is that your patch not only adds the
useless (and broken) feature to the existing syscall but also makes a
permanent change to the public interface for your own use.  That's
what I'm against.  So if you stop touching the struct timex, I won't
complain anymore.
