Good catch.

I wonder if icu4c should instead depend on ‘tzdata-for-tests’, which is
changed less frequently to avoid full rebuilds?  Maybe Leo can comment.

I hope icu4c also honors the TZDIR environment variable, which would
allow users to have it refer to the latest version.  Do you know if
that’s the case?

Last thing: this would probably be for ‘core-updates-next’.

Thanks,
Ludo’.
