Title:
  Wrong timezone detection (always UTC)

Status in tzdata package in Ubuntu:
  Fix Committed

Bug description:
  With tzdata 2024b-1ubuntu1 (plucky-proposed), the timezone is wrongly
  detected to be UTC, no matter what I do.

  This is working fine with 2024a-4ubuntu1, which is what was released
  in Oracular.

  Simple reproducer:
  ```cpp
  #include <chrono>
  #include <iostream>

  int main() {
      const std::chrono::zoned_time cur_time{ std::chrono::current_zone(),
                                              std::chrono::system_clock::now() };
      std::cout << cur_time << '\n';
  }
  ```
  Compiled with `g++ -std=c++20 main.cpp`

  ```
  $ ./a.out
  2024-10-21 16:14:17.489489001 UTC
  $ dpkg-query -W tzdata
  tzdata	2024b-1ubuntu1
  $ sudo apt install tzdata/oracular
  [...]
  $ dpkg-query -W tzdata
  tzdata	2024a-4ubuntu1
  $ ./a.out
