RTC Sync Question in V6

General Beta 6.0
1

I'm getting ready to start playing with V6 in a network that is currently running a chrony server to handle NTP for some cameras without network access. This is going to be on a PI 5 with an RTC Clock. The PI currently handles writing time to the RTC file. Am I correct that option for updating RTC can be left off in this case?

ntp.sync.rtc.set
Should FTL update a real-time clock (RTC) if available?

Sure, but it also wouldn't harm. The RTC has an accuracy of only +/- 1 second. When the RTC is already correct, Pi-hole will not update it. When you enable debug.ntp, you'd see something like

DEBUG_NTP: RTC time is already correct

in /var/log/pihole/FTL.log.
