java 8 Instant.now() is showing wrong instant time

In Java 8 Instant.now() method showing wrong time . My code looks like :

import java.time.*;
import java.time.temporal.*;
public class DateTimeDemo{
    public static void main(String []args){
            Instant now = Instant.now();
            System.out.println(now);
        }

    }

Its date part is correct but time part .

eg

2016-07-11T11:01:25.498Z but in my system it is 4.31 PM

I am using Asia/Calcutta TimeZone
