A new test suite has been added for libstdc++‘s chrono operator<< overloads, specifically focusing on formatted output semantics. These tests ensure that the implementation correctly handles sentry construction, padding with different alignments, width reset, and locale-aware output. This rigorous testing aims to confirm the robustness of the stream output for time-related objects.
