Picture this: A government announces a last-minute timezone change with just days of notice. Suddenly, your serverless application has the wrong time assumptions baked into immutable functions. Users get notifications at wrong times, business logic breaks, and support is flooded with "time bug" reports.

This happens 3-6 times per year as governments adjust timezone rules for political, religious, or economic reasons. In traditional servers, you'd update the timezone database and restart. In serverless? Your timezone data is frozen into deployment artifacts.

This lightning talk shows the one hybrid architecture pattern that actually works in production - preventing millions in downtime when governments decide to mess with time.
