Pax command help

Kris_5 — Fri, 02 Jan 2004 14:45:19 GMT

I am trying to extract a tar file using pax command and I need to retain the timestamp on the files.

pax -pe -rv <$t_tar_file

The tar file is generated on a Unix host which is situated in west coast of US. When I extracted the tar file on a Unix host which is situated in Europe (a time zone difference of 9hrs) the creation time of the file is changed to creation time at source + 9hrs (time zone difference).
Example file in source
------------------------
drwxrwsr-x 2 apps dev 96 Aug 14 17:10 rk3124

Example file in target
------------------------
drwxrwxr-x 2 apps dev 96 Aug 15 02:10 rk3124

Could some body help how to avoid the change in time stamp on the file in target machine. Thanks in adv.

The time is preserved, and is correctly interpreted by the target machine. It's supposed to work this way.

To see the time stamp as it is for US Pacific time zone, you would have to set the time zone for your session.

# export TZ=PST8CDT

Then do an 'll' and you should see the time stamps match.

HP-UX only keeps one time: GMT (aka, Zulu or UTC) and tar saves the timestamps in that time. When you list or restore the files, the timestamp is interpreted based on the current setting for TZ. So no matter where you restore the files, the timestamp is correct based on the location where they were saved. This is why users all over the world can login to an HP-UX system and with their TZ set to the local timezone, all date stamps will be correct for the local timezone.
