Setting Data Modification Times

Normally, tar sets the data modification times of extracted files to the corresponding times recorded for the files in the archive, but limits the permissions of extracted files by the current umask setting.

To set the data modification times of extracted files to the time when the files were extracted, use the --touch (-m) option in conjunction with --extract (--get, -x).

--touch

-m

Sets the data modification time of extracted archive members to the time they were extracted, not the time recorded for them in the archive. Use in conjunction with --extract (--get, -x).
