[LEAPSECS] CCTF reported to CIPM last month and it's interesting!

[Seaman, Robert Lewis - (rseaman)]

The need for solar timekeeping infrastructure is implicit (and sometimes explicit) in the multiple decades of this mailing list and related meetings and websites, e.g., https://futureofutc.org. “Requirements” was the first word of the title.

And if the more dramatic prognostications of commercial space come to pass and large numbers of people take residence on neighboring planets, they, too, will require solar time:

One hopes that funding and motivation to maintain and enhance UT1 will remain indefinitely. It is only a piece of the puzzle.

I see nobody anywhere suggesting that UT1 should not be measured
and maintained in the future (see for instance page 36)

But I also fail to see even the remotest outline of what the
"significant new infrastructure" you talk about might be or should do ?

Never attribute to malice what can adequately be explained by incompetence.
