Thought I just remind people that an alternative is to provide UT1 time, 
as Judah Levine had been doing on a NIST NTP server as a test of concept.

Then again, do regular testing of systems to see how they handle leap 
seconds and fix things until it works is also a quite workable solution.
That's what we done for our products and not been able to detect any 
issues with leap seconds per se.
