I better make a note in bugzilla. You could also take what you have learned so far to the systemd list, they're fairly responsive. You could ask if it's worth setting 'systemd.log_level=debug systemd.log_target=console' as a persistent boot parameter in case this problem happens again, since it's the highest level logger (debug logging in chronyd or ntpd may not catch the culprit). The systemd debug might be too aggressive is why I suggest asking. systemd can actually set time via timedatectl however on its own it's not responsible for setting time.
