ddiff does exactly this. However it never looks at any timestamp since it is the most unimportant/unreliable path component "tag" wrt. "what has been changed" and does also not take file permissions and xattrs into account. So ddiff is all about path names, types and content.

Probably the worst of all suggested alternatives ...
