That doesn't make any sense. When the ITU decides *not* do to something
it's equally informative as when they decide to do something.
Just to be clear you're saying everyone, including the CCTF (previously
cited) and the ITU, that says UTC is discontinuous is wrong?
For those wonder that "internal letter" from CCTF to BIPM notes that "The
UTC system as defined today is a *stepped* atomic time scale" [emphasis
mine] which is quoting the ITU and can also be found at <
discusses why the ITU continues to leave UTC stepped.
"UTC is a discontinuous time scale composed from segments that are linear
transformations of atomic time, the discontinuities being arranged so that
UTC approximated UT2 <https://en.wikipedia.org/wiki/UT2> until the end of
1971, and UT1 <https://en.wikipedia.org/wiki/UT1> thereafter."
