How It Works
This clock reads your device's system time and renders it using the browser's Intl.DateTimeFormat API. When you select a city, the time is converted to that city's IANA timezone — including automatic DST handling.
Full-screen mode uses the native Fullscreen API, making this perfect for classrooms, meetings, or as a desktop clock overlay.
