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

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

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