In this episode, Lucas and Luna tackle a surprisingly common issue: web apps that ignore the user's time zone. They explore how a major online calendar app once double-booked users across time zones, why many developers default to UTC without considering local contexts, and how a simple JavaScript shift can fix scheduling chaos. They also discuss two practical approaches—client-side detection with Intl.DateTimeFormat and server-side storage in UTC with local rendering—and the pitfalls of trusting the browser's unreliable time zone offset alone. By the end, you will know exactly how to avoid time zone bugs that frustrate users and cost businesses appointments.
