Worked on stabilizing date handling in the Submitty/Submitty discussion forum, focusing on backend reliability and user experience. Addressed a critical server crash by correcting MDY and DMY date parsing, ensuring consistent date rendering regardless of user preference. Introduced a raw ISO timestamp for internal logic, decoupling display formatting from backend comparisons. Updated Twig templates to align with DateTimeFormat conventions, which improved maintainability and reduced potential errors. Utilized PHP and Twig to implement these changes, laying the groundwork for future automated testing. The work enhanced forum stability and reduced user support issues, though no new features or automated tests were added.
