Source W32time, Event 29 Issues with this and it is not running

I am getting too many events that is telling me that there is some kind of problem with the time sync. If I am looking in Services then Windows Time is not there. The service is not even listed there? I have tried many things to change the time server source and ran some commands and now it is gone? Any ideas?

There are two levels, or tiers, of Network Time Protocol (NTP) time servers that are available on the Internet. The NTP is defined in Request for Comments (RFC) 1305. The first-level time servers are primarily intended to act as source time servers for second-level time servers. For more information visit this website - http://support.microsoft.com/?id=262680
