It seems the "adjust" function intentionally logs also calls/modes
that don't actually change anything. Can you please explain it a bit
in the message?

NTP/PTP daemons typically don't read the adjtimex values in a normal
operation and overwrite them on each update, even if they don't
change. If the audit function checked that oldval != newval, the
number of messages would be reduced and it might be easier to follow.
