Re: posix atime/ctime changes despite mtime being set

[Sergey Poznyakoff]

Hi Piotr,

The --mtime option does not affect atime and ctime. If you want full
binary compatibility, use also the --pax-option option, e.g.:

  --pax-option 'atime:=0,ctime:=0'

or

  --pax-option 'delete=atime,delete=ctime'

See the end of subsection "Controlling Extended Header Keywords" of the
GNU tar manual for suggestions on how to create binary equivalent archives
in POSIX format.  It is available online at:

Regards,
Sergey
