Perhaps the issue is that systems using musl don't include the tzdata package?
Not just glibc.
I also note a minor bug/issue with printf in Bash 5.3-alpha: the builtin printf treats TZ=CET-1CEST,M3.5,M10.5/3 as if it were oddly-named UTC.
Bash just calls tzset() and doesn't do anything else with $TZ. Any further
interpretation of the timezone data is there or in strftime(3).
