I use a Garmin GPS 18x with ntpd. Works fine, just make sure you flash it with the latest firmware (my model had an older firmware from before the 2019 week number rollover, which confused ntpd so it wouldn't accept the time). I also use a Meinberg C51 DCF receiver. Not as accurate as GPS, but also works fine. This model is EOL. I expect that the newer model (C600RS) also works, but I've never used it. Maurice
