You could just set up ntp to add 33 sec to its time, and you would have

Mark,
Details on how leapseconds are handled are in the NTP leapseconds
executive summary on the NTP Project Page linked from www.ntp.org. The
return code from ntp-gettime() reveals when a leap second is or is not
in progress. In the intended model, ctime or equivalant should notice

Martin,
In the current development code when the kernel does not implement a
leap function, the clock is stepped near the leap epoch. Here, near
means within one second early or late and yes, this can be considered
pinball behavior. This should probably be an option.

Spoon,
Assuming your incident was the beginnin of this year, no leap was
schedule nor should have been advertisec by any of your servers. The
current code, which you might not be using, takes a vote of the leap
indicators in all servers and requires a clear majority before
scheduling a leap.
Danny,
Good point; I agree. For experiment I parked the public group key for
pogo.udel.edu in the lists of public time servers. Next step is to
figure how to do that with the pool scheme.

I certainly did not mean to disparage NTP time. I

You might have better luck using the normal -O flags and figuring out which
math routines are needed, and then seeing if you can find some .s files that
will implement them.
Also, configure CCFLAGS='-O whatever' may be useful.

Steve,
You are correct; the new certificate is not used until after restarting
the daemon. When restarted the next upstratum a client automatically
restart the protocol (not the daemon). They all get well shortly after
sending the next poll. As this happens the client finds a more recent

Rick,
Apparently, OWAMP uses NTP timestamps, but the article assumes there is
a difference between NTP time and system time. Statistically, NTP
time is an unbiased estimator of UTC and system time is a lowpass
version of it. The offsets you might consider NTP time represent
