### Describe the enhancement requested C++20 finally defines standard APIs for calendar dates and timezones: https://en.cppreference.com/w/cpp/chrono.html#Time_zone However, some old gcc and clang versions that we might need to support [don't support](https://en.cppreference.com/w/cpp/compiler_support/20.html#cpp_lib_chrono_201907L) these APIs in full. So we would need to still our [`date` backport](https://github.com/HowardHinnant/date) on these compilers. The main point of doing this would be to (hopefully!) use the system-provided timezone automatically on Windows, while the user currently needs to install a timezone databases themselves. ### Component(s) C++ -- This is an automated message from the Apache Git Service.
