Libstdc++‘s timezone database now uses realpath to resolve the /etc/localtime symlink, addressing an issue where chained symlinks could prevent correct timezone identification. This change ensures that even complex symlink configurations correctly resolve to the underlying timezone file, allowing chrono::current_zone() to function reliably. The previous readlink-based approach could fail if /etc/localtime pointed to another symlink.
