Simple leap-second checker available
Folks, I wanted to know which of the servers I was synching to was sending

Hi
My setup is as follows:
Server A <--- GPS

Server B <--- HP cesium frequency normal
Server A gets it's timestamps from GPS.
Server B gets it's timestamps from Server A and PPS from the HP
cesium. Server A is marked as prefer because otherwise PPS won't work.
My problem is:
If Server A
