How Does the World Clock Work?

The world clock displays the current local time for 20+ major cities around the globe, updating every second in real-time. It uses the browser's Intl.DateTimeFormat API with IANA timezone identifiers, which means it automatically handles daylight saving time changes. Each city card shows the current time, date, AM/PM indicator, and UTC offset. Use the search box to quickly filter and find any city.
