However, to the approximation of tzdata, the outcome is the same: both country A and B would be shown in the tzdata file as having an offset of 60 minutes.

It is correct under ITU-R TF.460-6.
It will not remain true if the draft revision to that document is
approved in its current form at the Radiocommunication Assembly
next January.  Alternatively, the emeritus director of the BIPM
has suggested that the ITU-R should relinquish the definition of
UTC to the CGPM, and the result of that option is even less clear.
