Ah ok, now I understand. This should be easier in our case because system time is set every minute by "set system time SK plugin" which is already taken the time from any NMEA 0183/2000 source connected to openplotter. We should just share the system time by the ntp server.
Could anyone who has already done this in openplotter share an example?
