Applies to

  • NFSv3
  • NFSv4.x

Answer

Adding files to a UNIX directory modifies the directory file, adding the associated inodes of the child files created.  Thus the modified time is updated.

Additional Information

Clients have the ability to decide if/when mtime of a directory should be changed. See: rfc1813
