Thanks for the interesting read!
In your Conclusion, you say "the CGPM resolution also stipulates that no
change to current practices can occur before 2035."
This is not how I read read the CGPM document on the BIPM website:
"The General Conference on Weights and Measures (CGPM), at its 27th meeting
[...] decides that the maximum value for the difference (UT1-UTC) will be
increased in, or before, 2035,"
So in case the negative leap seconds become a real threat, according to my
interpretation is is an option to increase the tolerance value earlier than
2035 to avoid trying out negative leap seconds a last and first time.
Can someone confirm my view?
Best regards,
Jürgen Appel
