Is svndump guaranteed to dump revisions in order of incresing timestamp?

Is svnadmin dump guaranteed to dump revisions in order of increasing
timestamp?

Another angle on the same question: Is the timestamp of revision N+1
guaranteed to be not less than the timestamp of N?

I will add the answer to the dump-stream documentation.
