title: Trusted timestamping log files in Ubuntu 9.10
body: <p>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 <a href="http://en.wikipedia.org/wiki/Trusted_timestamping" rel="nofollow noreferrer">this page</a> but couldn't found a proper solution for my current needs. </p>
  
  <p>Is there any command to sign log files with a trusted timestamp in Ubuntu?</p>
  
  <p>Regards,
  Burak</p>
