Fellow time-nuts,
As David insisted that I get and then read the ITU Handbook Selection
and Use of Precise Frequency and Time Systems (1997) and in particular
Chapter 3 I took the time to get it and start reading it. In there I
found clause 3.3.2.4.4 Truncation effects, which addresses this

The two requirements are then mutually exclusive.
This is
