Is there any way to set the RTC without an NTP available? I have a non-internet connected device. On boot up, the Pi gets it’s location and time from a GPS module, but then puts the GPS in low power mode to save battery power. I would like for the Zymkey 4 to sync its time to the GPS time and maintain the RTC at this point. How can I achieve this?
