World Time is the best way to keep track of what time it is in different locations throughout the world.
★★★ NEW in World Time 4.0 ★★★
World Time is the first application that lets you pin your city to the start screen and show the time in that city... in real time... and you can ask Cortana to do this for you with voice commands such as 'World Time pin Toronto to start screen' or 'World Time add Paris'.
Its features include, among others the day/night map (terminator line) that is generated internally so it does not use the Data services, and Time Zone Calculator that allows you to easily check what time it's in other cities at a certain time of day.
The app is free, supported by ads and in app purchases. For more details check the settings purchases page
Choose from over 2000 cities to show the time with daylight savings and sunrise/sunset times.
