The field st_atime is changed by file accesses, e.g. by
execve(2), mknod(2), pipe(2), utime(2) and read(2) (of
more than zero bytes). Other routines, like mmap(2), may
or may not update st_atime.

The field st_mtime is changed by file modifications, e.g.
by mknod(2), truncate(2), utime(2) and write(2) (of more
than zero bytes). Moreover, st_mtime of a directory is
changed by the creation or deletion of files in that
directory. The st_mtime field is not changed for changes
in owner, group, hard link count, or mode.

The field st_ctime is changed by writing or by setting
inode information (i.e., owner, group, link count, mode,
etc.).
