Setting TimeZone Id of Default Timezone Example

The following example shows the usage of Java TimeZone setID(String) method to set the TimeZone id. We've created a TimeZone using America/Los_Angeles and then set its id to GMT+8 using setID() method. Then using getID() method, we've verified the result.

package com.tutorialspoint;

import java.util.TimeZone;

public class TimeZoneDemo {
   public static void main( String args[] ) {

      // create time zone object 
      TimeZone tzone = TimeZone.getDefault();

      // set time zone ID
      tzone.setID("GMT+08:00");

      // checking time zone ID
      System.out.println("Time zone ID:" +tzone.getID());
   }    
}

Output

Let us compile and run the above program, this will produce the following result.

Time zone ID:GMT+08:00
