I have both a GPS receiver and a real time clock on my Stellarmate/Astroberry. I don't know if that would solve your problem because I don't know how it is used. I would like to hear an explanation from the developers how the realtime clock and the GPS are handled. Specifically:
- Is the real time clock updated if there is time available from the GPS or the network?
- If all 3 time sources (RTC, GPS, Network) are available, which does Kstars use?
- Does Kstars do any evaluation of the quality of the time (latency) from the GPS?
- Is the RTC updated when time is set manually in Kstar or in the operating system?
- Does the system time get updated if the GPS reports time?
- Where does the system get the time if there is no network time server available?
