I can't reproduce your result.

unicorn:~$ mkdir tmp/leaf
unicorn:~$ find tmp/leaf tmp/leaf/ tmp/leaf//
tmp/leaf
tmp/leaf/
tmp/leaf//
unicorn:~$ find tmp/leaf tmp/leaf/ tmp/leaf// -printf '%T@/%TY-%Tm-%Td/%TT/%p\0' | while IFS=/ read -rd '' _ day time path; do printf '%s\n' "$path"; done
tmp/leaf
tmp/leaf/
tmp/leaf//
