If you're running UFS, the system clock should get set to the timestamp
in the superblock.   That will be the last sync before the previous
shutdown so it'll be minutes to hours out of date but that should be
recent enough for DNSSEC to work.

Note that this only works on UFS - see

As an alternative option, the RTC in both the Rock64 and RockPro64
are supported.
