I occasionally look at the machines and manually do
date --set with dsh. That way you know when you are
using the network bandwidth for setting up your clock :)
With clock skews sometimes you will have problems with
compiling programs with make, and debugging problems
(try asking a question: when did that happen? and it would be
difficult with a wrong clock).
