We had an AIX directory on which the client thought the ownership had
been altered.  I couldn't find an older copy of the directory so we could
prove their assumption.  As a test, I created a directory.  After it was
backed up, I changed the ownership and backed it up again.  As before, I was
unable to find a way to restore the directory to its previous ownership
rights.

What command allows one to see previous versions of a directory?

If this information isn't available, how can ADSM accurately do a point in
time restore?
