But have you actually tested to see if the change was really needed. 
Doing a diff and other various things aren't really telling you if 
something was broken in the first place.  I was given another java 
script, that works for all places I believe.

------
    import java.util.Date;

     public class TimeCheck {
       public static void main(String[] arg) {
	System.out.println(new Date(1173599999999L).toString());
	System.out.println(new Date(1173600000000L).toString());
	System.out.println(new Date(1194159599999L).toString());
	System.out.println(new Date(1194159600000L).toString());
       }
     }
------

So, for your case, you would complie this code and then run

/usr/java/j2sdk1.4.2_12/bin/java TimeCheck
   and then
/usr/java/j2sdk1.4.2_12.sv/bin/java TimeCheck

And see if they are the same or different.
