    About this skill

    Build timezone and date-boundary tests in a repo using Cursor. This skill inspects date parsing, UTC/local conversions, database filters, cron schedules, billing periods, expiry logic, reports, UI formatting, and existing tests; flags DST, off-by-one, locale, naive-date, and midnight bugs; then prepares safe test cases, small patches, and verification steps without changing production clocks or data.
