Answer 1

You need to set time zone and you will get desired result.

TimeZone.setDefault(TimeZone.getTimeZone("IST"));

Here is a working code.

import java.util.Calendar;
import java.util.TimeZone;  
public class Cal {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        TimeZone.setDefault(TimeZone.getTimeZone("IST")); // Add this before print
        Calendar c = Calendar.getInstance();    
        System.out.println(c.getTime());
        c.set(2007, 0, 1);
        System.out.println(c.getTime());
    }

}

As per Doc "Typically, you get a TimeZone using getDefault which creates a TimeZone based on the time zone where the program is running. For example, for a program running in Japan, getDefault creates a TimeZone object based on Japanese Standard Time."

SO when you running in different timezone it is using as default timezone. Hope you clear now. I attach doc. please read.
