Emerald Terra is a classic analog world-time face with a ring showing the times of 24 cities across the globe, against a rotating 24-hour ring.

The time for each city is properly adjusted for the Daylight Saving Time (also known as Summer Time), if any, at that location.

You can customize the city selection from our 80,000-city database (one city per timezone slot).

The cities selected are also displayed as dots on a world map, and the day, date, and month are shown in windows.

More information, and help for configuring the app, are available at the website listed here.
