Status in Source Package "openjdk-6" in Ubuntu: New

Bug description:
I have set my system time to EDT (as reported by the "date" command), but Java reports my timezone as GMT (as reported by "user.timezone" property).

To reproduce:
create a file named tzTest.java with these contents:
import java.util.Date;

public class tzTest{
  public static void main(String[] args){
    Date now = new Date();
    System.out.printf("RFC 822 numeric time zone indicator: %tz/%Tz\n", now, now);
  }
}

now run it:
java tzTest

Here's the result I see with openjdk 1.6.0-b10:
$ java tzTest 
RFC 822 numeric time zone indicator: +0000/+0000

Here's the result with gjc:
$ /usr/lib/jvm/java-1.5.0-gcj-4.2-1.5.0.0/bin/java tzTest
RFC 822 numeric time zone indicator: -0300/-0300
