ntpd has a default maximum poll period of 1024 seconds (or ~17 minutes).

I'd try to poll no often than that. Use an even longer poll period if
you can.

Don't start hammering on the server.

ntpd allows 8 missed polls to occur before a peer is considered to be
unreachable. You may wish to adopt a similar strategy.
