Ta to you and stevea for explanation.
However, for Virtual Machines, ntpd can be pretty useless. In my experience ntpd just cannot handle the massive drifts that happen in VMs (VMware Server).
Wherever possible I have been using ntpd on the host, and then use a cron job to run ntpdate against the VM host. I can also appreciate it would be unreasonable to blast the main ntp servers with a gazillion ntpdate requests, so getting the local host right and using the local host is critical.
Perhaps there is something else I am missing?
