Sounds good to me.

I disagree, because gettimeofday is a porting hassle in practice.
On some hosts, you must pass a second argument to gettimeofday,
which is either ignored or not (depending on the host).
On other hosts, you must pass only one argument to gettimeofday.
And some hosts don't have gettimeofday, or put it in some nonstandard place.
In Solaris, there are two versions of gettimeofday, one in libucb
and the other in libc, which can lead to linking hassles for those poor
misguided souls who still want to use libucb.

I don't bother with gettimeofday porting hassles any more.  If a host
has clock_gettime and if it succeeds then I use it; on older hosts I
fall back on 'time'.  This is easier to maintain, and yields more
precise results on modern hosts than gettimeofday would.  See the
source code to GNU make for an example of this approach.
