[LEAPSECS] drawing the battle lines

The BIPM website has a few new tidbits related to UTC.

They celebrate 25 years since the BIH was abolished, TAI
was transferred from BIH to BIPM, and Circular T was started.

They also celebrate one year since starting the new "UTCr".

And they have published the report of the 19th meeting of the CCTF
http://www.bipm.org/utils/common/pdf/CCTF19.pdf
in which there is a long discussion of the UTC shenanigans at ITU-R.

Concluding the report is Resolution 6 in which the CCTF declares what
UT1 is and is not, what UTC is, and what a time scale is in a fashion
that directly contradicts the 1976 IAU definition of time scale.

In particular, resolution 6 makes it plain that the count of days in a
calendar and the subdivision of those days is not a time scale if
those days are measured by astronomical means. In short, that
history, tradition, law, and common public perception about what time
is have been wrong.
