Yet LEAPSECS is like all the recorded discussions among various international agencies: no consensus.  The folks who are
determining policy among the various national bodies that contribute to WP7A have never participated.

 

The folks in the US body have sent me private nastygrams for pointing to documents which federal procedures require to
be public.  The astronomers from USNO who were attending AAS two weeks ago were warned about participation in the UTC
splinter session with reminder of the DoD policy memo.  The IAU working group on the issue is split with no obvious path
toward a document to contribute to the ITU-R.  The historical documents look like the same sorts of things were
happening during the 1960s.

 

Google has done the world a service by publishing its leap smear as an example of "how to", but its utility is
restricted to their non-real-time cloud.  The trouble logs at Amazon showed no indication that they experienced trouble
in 2012, so they probably worked out a scheme to handle any issues, we just don't know what it is.  The PTP folks are
using TAI-like time, and the vendors of off-the-shelf NTP servers provide configurations that give TAI-like or GPS time
even though there is no international regulatory basis for doing that.
