I was wondering how I can sync my router with a time server? Is there one on the Internet or can I simply use a my Windows Domain Controllers clock? It doesn't have any special clock program just its default clock.
The router uses NTP. Unless you install an NTP server on the DC it won't be a time source. A good source to pick is your ISP if they run a time server. It has the least number of hops to your router. Otherwise you could check the NTP pool project http://www.pool.ntp.org/ It explains how you can choose multiple servers for time synchronization.
NTP is the "full" network time protocol. SNTP is the simple variant which is not so complex but also not so accurate. NTP is used for highly precise time synchronization. If you configure two or more computers as peers they synchronize to each other increasing stability through each other's feedback.
SNTP on the other hand is simplified version of NTP mainly used to synchronize the clocks on clients to a server. It is just a simple poll which is enough at places where you don't need a very precise clock.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
