What is the "unacceptable risk"?? Just what are we risking? We have had Leap Seconds since 1972, and after 42+ years we
seem to be doing OK!

Just after the WP7A activity in Geneva earlier this month the CGSIC declared that leap seconds are unacceptable risk.

Their history neglects that initial need for leap seconds was to satisfy the demands of the IAU and navigation community
that the radio broadcast time signals *must* provide Universal Time.


I wonder if the ITU-R process can go to its completion without introducing any document which points out that to omit
leap seconds from a time scale called UTC is to redefine the word "day".
