Seems the time server on one of my SBS 2008 systems decided to run 10 minutes fast this past week. After resetting the time, it proceeded to run 10 minutes fast again.

This will display the following output (it will either be: Local CMOS Clock or time.windows.com)

I wanted a reliable time server and found the pool.ntp.org. As the name implies ntp.org is the home of the Network Time Protocol open source project. Members work together to provide a public pool of time servers for use by individuals and businesses. Because the servers operate in a large network of pooled resources the time servers are highly redundant and reliable.
There are several pools of NTP servers for you to choose from based on what part of the world your server is located. Select your region from the list in the link. http://support.ntp.org/bin/view/Servers/NTPPoolServers
Clicking through you’ll see that in North America, there’s us.pool.ntp.org, ca.pool.ntp.org, mx.pool.ntp.org and so on with 609 active servers in the pool. In Europe there’s a pool for every Country as well with 1386 servers total.
