I noticed an issue with GPSD module when using a gps dongle on my single board computer
As you can see in the attached image, the UTC time retrieved by the GPSD INDI module is different from that shown by cgps and the system time (which was synced to the gps time with a python script).
Even if I manually set time and date in Kstars, after a while, the auto fresh sets it back to the wrong time.
