That would be nice it is were a standard and everybody was doing it, because
otherwise, for a day, your own network might be happy, but if you have any app
that needs to communicate with the outside world, you are in a lot of hurt.

Time Technology and leaping seconds
http://googleblog.blogspot.com/2011/09/time-technology-and-leaping-seconds.html
"The solution we came up with came to be known as the “leap smear.” We
modified our internal NTP servers to gradually add a couple of
milliseconds to every update, varying over a time window before the
moment when the leap second actually happens. This meant that when it
became time to add an extra second at midnight, our clocks had already
taken this into account, by skewing the time over the course of the
day. All of our servers were then able to continue as normal with the
new year, blissfully unaware that a leap second had just occurred. We
plan to use this “leap smear” technique again in the future, when new
leap seconds are announced by the IERS."
