Fixing Time Sync problem in Xen DOMU on Oracle VM Server

A 0 in the following suggests syncing time with DOM0:
/proc/sys/xen/independent_wallclock

However, when DOMU is unable to keep time sync with DOM0, the following may be tried:
echo 1 > /proc/sys/xen/independent_wallclock

If you have a ntpd setup elsewhere:
/usr/sbin/ntpdate <ntpd_server>

To update over the network:
rdate -s http://time-a.nist.gov

To manually set the date:
date -s "<date>
