The system clock in a paravirtualized kernel cannot be set.  The hardware 
clock in an HVM domU also cannot be set.  The hadware clock and the system 
clock for paravirtualized domUs is controlled in dom0.

I really like this, as I can set up NTP in dom0 and all of the clocks will be 
in sync in my domUs, just like that.

I don't know of any way to configure a domU to be able to control it's own 
clock separately, other than taking out the source and updating the code to 
give you that option.  I wouldn't bother.
