why isn't there an easy way to identify the release version of an installed tzdata tree?
$ head -n 1 /usr/share/zoneinfo/tzdata.zi # version 2021b I ran this shell command on my Fedora 34 system, which I updated a few days ago from the Fedora project by using the "dnf update", a standard way to keep up-to-date. Unfortunately this tzdata.zi approach is not taken by every distribution. Also, it's reasonably common for distributions to say "2021b" (or whatever) even though the actual data contains minor modifications from vanilla 2021b. The modifications are typically so minor that almost nobody cares about the differences (though evidently somebody does :-).
