To that I'd like to add:
- Use your ISP-s ntp servers if possible. Try 'ntp.provider.domain'.
- do NOT use 2 clocks, better use 1 or 3 or more. (with 2, ntp cannot
check for the best time)
- see http://www.pool.ntp.org/: you can use 'pool.npt.org' and variants.
If you have more than a couple of internal servers, create a clock-tree
inside: 3 or 4 machines using external references, all internals use
those machines.
If the number of machines is relative large, group machines and define
machines in the group as each other 'peer' clock (use "peer" in stead of
"server").
