[tz] CCTF survey on Time and Frequency Metrology - Telecom

[Paul Eggert]

I replied to that survey, basically saying that currently our work is 
based on two timescales (TAI and UTC) and that I hope they don't turn it 
into four (TAIold, UTCold, TAInew, UTCnew).

Or would it be three? That would be even more confusing....
