I have RPi setups with RTC or GPS w/PPS.
I'm just wondering which is the better setup for maintaining accurate time.
Does the RTC get updated regularly via the NTP source on the Internet?? Or is the time stored in the RTC only provide time during boot/lack of NTP source?
On my other system.? GPS w/PPS provides accurate time but it takes a few minutes to achieve this fix.
I was just wondering.? I'd like to configure my RPi's the same.
Any assistance would be greatly appreciated.?
