Jeroen,
Running ntpd inside a virtual machine is not problem free, atleast not on *nix. 
ntpd saves stats for how much your system differs from your referance clock(s) 
and tries to make smart decisions for how much your clock is differing when 
adjusting the local clock. This works well for a physical system, but in a 
virtual machine where timing is not equally reliable these assumptions will be 
incorrect and make your clock go even more wrong. Running ntpdate from cron is 
however a working workaround. ntp in windows is also not as smart and doesn't 
have as much side effects.

Because of this it's normally better to run ntpd on the host system, and sync 
the virtual machines to the host system through pit and VMware Tools.

Why not have your clock sync with a time server (pool)? Then you
wouldn't have these problems I'd think.
