public class Calendar_Demo { 
    public static void main(String args[]) 
    { 
        // Creating a calendar object 
        Calendar calndr = Calendar.getInstance(); 
  
        // Getting the time zone of calendar 
        TimeZone time_zone = calndr.getTimeZone(); 
  
        // Displaying the current time zone 
        System.out.println("The current Time zone is: "
                           + time_zone.getDisplayName()); 
    } 
}

输出：

The current Time zone is: Coordinated Universal Time

示例2:

// Java code to illustrate 
// getTimeZone() method 
  
import java.util.*; 
  
public class Calendar_Demo { 
    public static void main(String args[]) 
    { 
        // Creating a calendar object 
        Calendar calndr = Calendar.getInstance(); 
  
        // Getting the time zone of calendar 
        TimeZone time_zone = calndr.getTimeZone(); 
  
        // Displaying the current time zone 
        System.out.println("The current Time zone is: "
                           + time_zone.getDisplayName()); 
  
        // Changing the time zone 
        calndr.setTimeZone( 
            TimeZone.getTimeZone("GMT")); 
  
        System.out.println("New TimeZone: "
                           + calndr.getTimeZone() 
                                 .getDisplayName());
