That makes perfect sense, but it still breaks our compatibility policy
by making people fix their code when they upgrade. There are a lot of
functions in the public Subversion API that I'd LOVE to change to make
them "better" in some way, but I can't because people are already
using them. Aren't there potentially already people using the
Dirent#time method from 1.3.x who are assuming it returns an integer?

So, in short, no argument that it's a better API, but that doesn't
make it right.
