A DESCRIPTION OF THE PROBLEM :
It seems that creating a new GregorianCalendar and then calling setTimeZone() before calling getTimeInMillis() causes the date to be changed. Please take a look at the included example.

This is happening with all versions of Java that I have tested.

Thanks!

REPRODUCIBILITY :

---------- BEGIN SOURCE ----------
import java.util.Calendar;
import java.util.GregorianCalendar;
import java.util.TimeZone;

public class TimeTest {

    public static void main(String[] args) {

        Calendar calendar = new GregorianCalendar(2004, 4, 1, 12, 0);
        calendar.getTimeInMillis();
        calendar.setTimeZone(TimeZone.getTimeZone("GMT"));
        System.out.println(calendar.getTimeInMillis());

        Calendar calendar2 = new GregorianCalendar(2004, 4, 1, 12, 0);
        calendar2.setTimeZone(TimeZone.getTimeZone("GMT"));
        System.out.println(calendar2.getTimeInMillis());

    }

} // TimeTest
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
The Calendar.getTimeInMillis() method must be called before the Calendar.setTimeZone() method.
