Description

In ARROW-13168, we enabled setting the path of the text-based database engine at runtime. This allowed R to use the tzdb package for the timezone database, since it uses the text format.

However, it doesn't seem like tzdata Python package ships that text format. They do have a "compact" text format, which might be compatible with our vendored date library. Otherwise, we'd likely have to wait for binary format support in https://github.com/HowardHinnant/date/issues/564
