This worked for me when I tried it.  I tried it on 14.2R with both
/usr/bin/tar and /usr/local/bin/bsdtar and both produced the desired
result.

I did this to test it.

    rwp@madness:~/tmp/junk$ rm -rf dir1
    rwp@madness:~/tmp/junk$ mkdir dir1
    rwp@madness:~/tmp/junk$ touch -t 197001010101 dir1/file2 dir1

Could you test this more on your system?
