Could it be that the zoneinfo format has changed so that musl is not
compatible any more?
I suspect this:

Changes to build procedure
The Makefile now defaults POSIXRULES to '-', so the posixrules
feature (obsolete as of 2019b) is no longer installed by default.
The last zoneinfo version bump was really simple (like always), but
possibly the internal format has changed so that musl libc isn't able to
read it any more.
Possibly musl uses that posixrules item to read zoneinfo?
I tested compiling both 2020a and 2020b, and noticed that the data files from
2020b were really short.
I compared Europe/Helsinki from 2020a and 2020b, and noticed a large size
difference:
481 bytes (2020b) vs 1900 bytes (2020a).
See differences in
https://github.com/openwrt/packages/pull/13644#issuecomment-712312797

Looks like 2020b is missing 3/4 of the earlier contents, and apparently musl
needs to removed deprecated data/functionality.
Helsinki timezone was applied ok with 2020a, while with 2020b "date" shows
just GMT/UTC time:

I have reverted the zoneinfo 2020b version bump in the packages repo for now.
There is now the old 2020a.
