Hello Paul,
okay I missed that. I just used the default configuration, but it
complained about missing rtc support anyway until I modprobed genrtc (rtc
does not work).

No... it uses automatic network configuration via guessnet and ifplugd.
Network is down when no network is available.
So I may be better off using the IP addresses of some NTP servers?
I just don't get it how chrony can tell me my system clock is 0.0 seconds
ahead of NTP time, while "sources" show that there are three sources
available and just to make completely sure I manually put it online by
issuing "password blabla" and "online" and the system clock is definately
several minutes behind NTP time... well sure its not fast of NTP time
then but shouldn't chrony adjust the clock anyhow, like it sometimes
does?
I just install ntpdate right now, run it once and sure the clock is right
up to the second with my radio controlled solar alarm clock. Why do
chrony and openntpd fail to do that for me?
Well probably worth a bug report and further investigation, but that will
have to wait until I manage to take the time for it.
