Anyone know where to investigate this further?
The linux app that syncs to the hardware is "hwclock" (which has various obscure parameters described in the man page).
You could make a script to sync with hwclock then reboot and see if the time is more in sync when it comes back. That would verify it isn't being synced (but, unfortunately, wouldn't help track down where the hwclock call ought to happen).
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.
