Sincerely,

I know I can do that to the config file but then it takes forever to synchronize. As I said, the idea was to not give a min/maxpoll so that ntpd would converge on a clock adjustment quickly (polling once ever 64 seconds) and then, after a couple days, I could throttle back the polling interval without restarting the server and changing the configuration file.

"Takes forever" is the problem you should try to solve. With the systems here, which have a GPS/PPS ref clock, they are synced within a minute of NTP starting, although it takes longer to get the ultimate accuracy. What version of ntp are you running, what OS, and what ref clock?

Cheers,
David
