Hi,
As Mark have said, you can buy an RTC. For how many months right now my
standalone (not connected to the internet) Raspberry Pi 4B has been very
stable with time using DS3231 module
https://shopee.ph/DS3231-Mini-RTC-Module-i.18252381.315148783. Sharing to
you as well https://marc.info/?t=15981
You can even get a Zigbee module combined with an RTC, and optional even
PoE if you want.

Hi,
this is a simple driver for the heartbeat status LED found on many ARM
boards. I find it quite useful on headless systems to see if the kernel
has booted, is still running or has shut down.
I am not sure if this driver is worth being included in the kernel. Still
I am sharing it here with any
Adding an RTC is definitely a solution, but the functionality to
support RTC-less boards is there in ntpd—and indeed works well when
connectivity is available from boot—it just doesn't work when network
access is delayed.
I'd also rather use ntpd than rdate, since the former uses constraints
to ch
