Generally the output time from these receivers via the serial port isn't very good from a precise time keeping point of view. There's about 10ms of variation in the reported time, which makes them very very noisy for the sort of work that ntp does. For a local network, it shouldn't be too bad, but expect to see a lot of strange things happen because the error can be so large.
