[CentOS-virt] Time lagging on DomU

on one of our systems I see that while the time on the Centos 5.4 Host is 
correct it lags behind on two of the 5.5 guests by almost 5 minutes but is 
correct for the third domU. From what I understand the clock of the system 
is controlled by the host and and guest cannot write to it (and because of 
that not change it). Does anyone now what the cause could be and how I can 
fix the time for the guests?

Running kernel versions:
Host (correct time):  2.6.18-164.15.1.el5xen
guest 1 (correct time): 2.6.18-194.3.1.el5xen
guest 2 (wrong time): 2.6.18-194.32.1.el5xen
guest 3 (wrong time): 2.6.18-194.el5xen
