Hello,

The documentation is correct. The reference file's mtime is compared
against the tested file's {a,c,m}time}
~~~
ametzler@argenau:/tmp/findtest$ for atime in 2000-01-01  2005-01-01 ; do for mtime in 2000-01-01 2005-01-01  ; do touch -m --date=$mtime m${mtime}-a${atime} ; touch -a --date=$atime m${mtime}-a${atime} ; done ; done
ametzler@argenau:/tmp/findtest$ ls -l ; echo atime ; ls -l --time=atime
