The Clock-Block is a clock generator that is useful if you want to replace the computer's onboard crystal clock with an external high-stability source.  For example, you can configure it to take a 10 MHz input from a GPSDO and create a 14.318182 MHz output to replace the crystal in a PC that uses that frequency.  The external clock improves the NTP system's short term stability because the typical PC crystal is quite temperature sensitive and overall just isn't very good.

You do not need to use something like the Clock-Block to build a very good NTP server, but if you want to build the *ultimate* server it is part of the mix.
