+Although the `nmea` reference clock driver is obsolete according to [https://ntpsec.org/removal-plan.html](https://ntpsec.org/removal-plan.html), it works perfectly for me, in particular better then the other drivers. However, maybe I was not trying hard enough with the others.
+
+The server has been joined the NTP pool, the statistics are available [here](https://www.ntppool.org/scores/93.241.86.156).
