> FYI: `tz.cpp` doesn't use tzdata (`.../zoneinfo/...`) from conda on Windows. It uses raw https://www.iana.org/time-zones data I don't understand the distinction. What's expected to be under `PYARROW_TZDATA_PATH`? We should be able to put whatever is required there. For context, it worked for `orc` (even upstream, not just in conda-forge) to use a conda-packaged `tzdata` (if available). In conda-forge itself, we're able to point `libstc++` to our tzdata as well, and will do the same for `libc++` once the C++20 `<chrono>` implementation becomes non-experimental (because we cannot patch the static `libc++experimental.a` without creating attack vectors). > Solution: Update bundled datetime. That sound like a reasonable first step. Medium term, it's also conceivable to move to C++20 facilities. -- This is an automated message from the Apache Git Service.
