Add comprehensive documentation for handling datetime timezone discrepancies between backend and frontend. The issue arises when backend returns naive datetime strings without timezone suffixes, causing JavaScript to parse them as local time instead of UTC. The guide includes problem description, root cause analysis, three frontend solutions (dayjs UTC parsing, manual 'Z' suffix addition, and global Axios interceptor), backend context, and testing checklist.
