In general, ntpd tries to use the best clock. It normally does a pretty good job of that. It isn't setup to read beteween the lines and do what you think is best. It gets that from the raw data with a lot of filtering and heuristics. I haven't looked at the code for the HBG receiver, but it should treat each bit as a one second marker, just like a PPS signal. Yes, it will have to wait until it gets a whole message to get locked up, but after that it should know the time for each tick. The refclock driver support code has a 64 slot FIFO and code to discard outliers so you shouldn't have to worry about the 59 seconds between complete messages. > server 127.127.22.0 minpoll 4 maxpoll 4 Why are you adding the minpoll/maxpoll? -- These are my opinions, not necessarily my employer's.
