VMware guest time sync under OSX

To sync time without needing VMware tools, you can run a cron job every minute that syncs with the OSX time daemon.

1. Determine the IP address that OSX uses for the VMware network
2. Add a cron job in the guest that runs
   
   ntpdate -s {ip address}

I'm running this in Ubuntu 8.10 under OSX 10.5.7 VMware Fusion 2.0.5.
