When a mocked directories contents change the mocked parent directly mtime should also be updated.

The standard filesystem behavior on linux is to update the parent directory mtime when the contents of the directory change. It would be helpful if this mock system implemented that interaction behavior as well to test certain use cases.

This seems to be the expected behavior: https://serverfault.com/questions/388050/does-directory-mtime-always-change-when-a-new-file-is-created-inside

sounds right. I think we may not be updating the time on the file object either.
