If you are interested in a hardware solution you can add an RTC to an RPI4 quite cheaply.

For example: https://core-electronics.com.au/ds1307-rtc-module-with-battery-for-raspberry-pi.html

I needed the trick from this thread to get it working though:
https://lists.freebsd.org/pipermail/freebsd-arm/2021-May/023713.html

I also needed a dtso based on this: https://github.com/seiyo/freebsd-rpi-b-ds1307/blob/main/ds1307.dtso
(Also changed brcm,bcm2708 to brcm,bcm2385)
