Here is my observation for NTP 'chronyd'. The NTP setup is based on 1PPS
(from Trimble TB) and kernel extension (pps_core)
As leap second event happens, I noticed the "system clock" (NTP machine)
was one second behind.
Then it took around 16 minutes for 'chronyd' to gradually align system
clock to match the time. Now everything ticking in tact.
Here is par of 'chronyd' log. I noticed four column changed from "+" to
"N"

For the LH 5.0 - it took the snapshot.

Alsom I noticed that LH 5.0 watch is little bit behind of the 'xclok'
watch translated from NTP (and from this link https://uhr.ptb.de/).

Fellow time-nuts,
While not fancy by any means, my laptop captured the leap-second

What NTP is this?
There is security patches to be made to older NTPs.
I had to shut down xntpd on several solaris machines to make them
safe, as there was no way of configure them to become safe. That was a
couple of years ago.

Ehm. While off-topic, let me tell you that we had to shut down the
last Solaris machine we had on the computer club because we concluded
that there where tools designed to target that generation of Solaris
machines and take them over. It should not see public internet if
powered on.
The network is increasingly hostile, so patch your machines, and don't
let any machines sit on public network unless you can patch them
regularly and also do that.
Cheers,
Magnus
