The main standard says a leap second is allowed in any month. That's what
the reference ntpd does.

Chris,
Thank you for these helpful advises. I am recalling many years ago there were
such things as line transceivers that converted the signals from TTL-RS232 and
backwards. Do these still exist in the world and have you perhaps these part

One of my internal NTP servers has the leap flag set to 01. The fake leap
second issue was produced in the servers where this NTP server is the time
source preferred, so I guess that it was my problem.
In order to check the leap
There are over 10 stratum one's that advertise LI=1 as of Wed Aug 1

Steven, can you point me to one of those servers? The ones that I've checked
all seem to have LI=0.
Thanks!

Sorry for jumping in so late.
In my opinion the basic concept of the local clock driver was good, easy to
configure, sufficient for small, simple networks, and it just worked as
expected in older versions of ntpd.
As David Woolley has pointed out in one of his comments, the local clock can
If you can, get a high speed scope (10MHz) and put it on the end of the
line and see what voltages are coming out of the line to the serial
port. You might find it is only a volt or less which is not enough to
drive the latches.
