Define "perfect match". I do not think we can really tell if we have an
exact match or not; the libc timezone API is just too limited to be
sure. And on many platforms we can be sure we will never have an exact
match, especially if we look at years before 1970.
If you want something in the log I'd be inclined to just always make a
log entry when we infer a timezone setting.
