Dear time standard enthusiasts,

Stan Cooper let me know about this information regarding the 
decades-long effort to eliminate or redefine UTC.

The Consultative Committee for Time and Frequency (CCTF) has prepared a 
questionnaire concerning several issues of time metrology:

 1. Updating the Roadmap for the redefinition of the second
 2. Leap seconds in UTC - building a consensus for a continuous timescale
 3. Promoting the mutual benefit of UTC and GNSS
 4. Sharing resources to improve international timekeeping

If you have opinions on these matters, CCTF would like to hear them by 
January 31, 2021. I copy the request from CCTF, below. The URLs got 
clobbered when I received the email, so I repeat here the working links:

The questionnaire also has links to more information about this, on the 
BIPM website.

> Dear Colleagues,
>
> The Consultative Committee for Time and Frequency (CCTF) has prepared a questionnaire concerning many important issues of time metrology, in particular the time difference between UTC and UT1, and is thus of primary importance for IERS. To make sure that the needs and wishes of astro-geodetic community are integrated into the general debate, you are strongly invited to respond to this questionnaire.
