- Set explicit UTC timezone globally in jest.config.ts and setupTests.ts
- Mock Intl.DateTimeFormat to use UTC by default while preserving prototype
- Replace regex patterns with exact values for declarative assertions
- Remove complex date formatting computations in tests
- Use fixed dates (2025-01-15T10:00:00.000Z) for consistent test results
- Fix EventDisplay.test.tsx to use exact time values instead of regex
- Replace 'Meeting link generated' text with 'Join Visio conference' button
