A "cesium clock" don't knew it should do leap seconds unless you tell
it, and it only affects the display and the internal time of the
clock.. -:)  The S1 NTP server and it's host OS has to be told to set
the leap-second indicator by hand to.. 

But all the system on the internet has to knew what to do with this
information. 

In the case of a host_os that do not knew about leap-seconds, NTP will
have the correct time and then try to stear the host as fast as it can
to loose/gain a second..
