Trusted timestamping log files in Ubuntu 9.10

We have an ubuntu 9.10 server. There are some log files need to be archived and they must be timestamped to guarantee no change in time. I've found this page but couldn't found a proper开发者_如何学Python solution for my current needs.

Is there any command to sign log files with a trusted timestamp in Ubuntu?

First you need to have a TSA or a timestamping authority in your network to call to timestamp do you have one? try http://www.opentsa.org/
