You can forget Wall St. firms and Banks for starters.
They need sub-microsecond accurate timing as some instruments (Forex)
are moving to <10 microsecond latency from order entry to order ack.
Although some software (FIXX) needs a lot of work to get there, they
are moving in that direction.

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.

Subject: [time-nuts] Google NTP Servers and smearing leap seconds...
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."
