Other time server/souce?
Unfortunately, it is not possible to enter an NTP server in RS; that's stupid... Because the log file shows that RS almost always cannot reach the specified pool "*.debian.pool.ntp.org" (error in name resolution / all other systems can reach it...).
In my opinion, it also makes no sense to use an external time-server if an NTPd is available locally; often the router itself or (as in my case) a NAS, which gets the correct time over the Internet from a German pool, compares it with the time received via GPS and the disciplined rubidium oscillator that is also available here and offers it in the LAN.
So the question is: which file do I have to touch to change the default?

Looks like changing /etc/systemd/timesyncd.conf with new fallback servers can do the trick.
