Here is the relevant part from my log:

What is the "freq" and "ppm" values ?

I don't see an obvious leap second in there.  Is it correct to state
that NTP did absolutely nothing to adjuyst the clock between those two
log entries ? Or would have more frequency contacts with the remote NTP
server and adjust the clock at greater frequency than log file entries ?
