Getting OffSet of SimpleTimeZone of India Zone Example

The following example shows the usage of Java SimpleTimeZone getOffset() method to get the offset of a SimpleTimeZone object from UTC. We've created a SimpleTimeZone using India. Then we've retrieved the offset and printed it.

package com.tutorialspoint;

import java.util.GregorianCalendar;
import java.util.SimpleTimeZone;

public class SimpleTimeZoneDemo {
   public static void main( String args[] ) {
      
      // create simple time zone object 
      SimpleTimeZone stobj = new SimpleTimeZone(720,"India");

      // get offset
      int offset = stobj.getOffset(GregorianCalendar.AD, 2000, 10, 2, 4, 5000); 

      // check offset value       
      System.out.println("Offset is : " + offset);
   }    
}

Output

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

Offset is : 720

Getting OffSet of SimpleTimeZone of US Zone Example
