Enable Time Sync from inside a Linux VM

Note to self: Command to enable VMware Time Synchronisation on a Linux VM without a GUI (with VMware Tools installed):
vmware-guestd --cmd "vmx.set_option synctime 1 0"
To disable it you have to turn around the last two parameters, like this:
vmware-guestd --cmd "vmx.set_option synctime 0 1"
If you want to apply a setting that is already current you will get the message:
"Invalid old value"
This is tested on RedHat Enterprise Linux 5 and SUSE Linux Enterprise Server 10. Source: Timekeeping best practices for Linux on kb.vmware.com
