I think it's a linux/freebsd i386 sysctl that decouples the domU clock from the host, but I'm not too sure about this. According to that logic it wouldn't make much sense for it to exist on the dom0, but then again I may be misunderstanding something. Not too familiar with the inner details on how the OS keeps time. Perhaps a developer on freebsd-xen could add some insight ? Regards, Hugo
