Marketa, from the perspective of the OpenSuse user I am fully satisfied
with the solution.

In fact I expected 'sudo zdump --version' to return the database
version. But the man page is unspecific in its description.

>From the perspective of the zdump user, the current situation is not
that good. I think all distributions should return similar output. And
the output should contain the tzdata version. Only that way it is
possible to evaluate the output in portable scripts.

Proposal (for a future version >2020a):
$ sudo zdump --version
zdump (GLIBC 2.28) - tzdata 2020c
