Maybe add an ExecStop= option to the chronyd.service with the appropriate parameters?

FWIW, on my rather old HP system I too get "System clock wrong" on some (not all) reboots.
A quick look and I estimate the average for this system is about 6 seconds.

The discrepancy is noted within 2 seconds of boot.  I wouldn't have noticed it if Sam hadn't
pointed it out.
