Mtime
From Hackepedia
Time of last modification of a file, the information is taken from the inode.
$ stat -s disk | tr ' ' '\n' | grep mtime st_mtime=1130490970 $ date -r 1130490970 Fri Oct 28 11:16:10 CEST 2005 $ ls -lT disk -rw-r--r-- 1 root wheel 33554432 Oct 28 11:16:10 2005 disk
If a file has been modified the mtime will change to that date.
