This will disable it from occurring from the Event log.
Before you change your current time source on any Windows server 2008 versions or SBS 2011, run the following command prompt to see wat the current time source is being used.
w32tm /query /status

w32tm /config /manualpeerlist:au.pool.ntp.org
For instance, au.pool.ntp.org is the preferred NTP source that I have used, you may change this to your preferred NTP Server. You can do a Google search for NTP servers to give you a list of others that may be available.
After you have run the command with your preferred NTP source, type in the following command
net stop w32time
Then press enter. Type in
net start w32time
Then enter. Type in the following command again to see if it has changed.
w32tm /query /status
Above you can see that the source has changed to au.pool.ntp.org
If you still see CMOS clock, allow it some time to sync.
You can also run this command to rediscover the time server
w32tm /resync /rediscover
