I would like to get my server time as close to GMT (Greenwich Mean Time) as possible. What is best way to do this?

It's Ubuntu 10

Well, I can think of two things you might mean:

  1. Set your timezone to GMT (UTC). You can use sudo dpkg-reconfigure tzdata to pick the right timezone.
  2. Keep your time as accurate as possible: Install the "ntp" package. I believe the defaults are good on Ubuntu 10, but you may want to edit /etc/ntp.conf and add a few lines like server and server; you'll want 4 or more of those. You'll have to restart the ntp service for those changes to take affect.
