Specs do say so.  timespec is { time_t tv_sec; long tv_nsec; }
(POSIX.1-1996).  timeval is { time_t tv_sec; suseconds_t tv_usec; }
(draft POSIX.1-200x).  suseconds_t is a signed integer type capable
of storing values at least in the range [-1, 1000000].

So you can change the type of tv_usec (but shouldn't, because it is
specified to be long by old defacto standards), but you can't change
tv_nsec (and neither can standards, because it is specified to be long
by old standards).
