How to display time zones?

To display the available time zones in Linux, you can use the timedatectl command or the getAvailableZoneIds() method in Java. Here’s how to do it using both methods:

Using timedatectl Command

Open your terminal and run the following command:

timedatectl list-timezones

This will display a list of all available time zones.

Using Java

If you want to display time zones using Java, you can use the following code snippet:

import java.time.ZoneId;

public class TimeZoneDisplay {
    public static void main(String[] args) {
        System.out.println("Available time-zones:");
        ZoneId.getAvailableZoneIds().forEach(System.out::println);
    }
}

This Java program will print all available time zones to the console.

You can choose either method based on your preference or the context in which you are working.
