FULL PRODUCT VERSION :
java version "1.4.1-beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1-beta-b14)
Java HotSpot(TM) Client VM (build 1.4.1-beta-b14, mixed mode)

FULL OPERATING SYSTEM VERSION :
Microsoft Windows 2000 [Version 5.00.2195]

A DESCRIPTION OF THE PROBLEM :
sun.util.calendar.ZoneInfo, which is used as the TimeZone class in java.util.GregorianCalendar, does not return a modified offset in case of daylight savings when getOffset() is called for the following case:

GregorianCalendar c = new GregorianCalendar(95,5,1);
int offset = c.getTimeZone().getOffset(c.get(Calendar.ERA),
                          c.get(Calendar.YEAR),
                          c.get(Calendar.MONTH),
                          c.get(Calendar.DAY_OF_MONTH),
                          c.get(Calendar.DAY_OF_WEEK),
                          c.get(Calendar.MILLISECOND));

In jdk 1.4, 1.4.1-beta the offset is -28800000, in jdk 1.3.1 it is -25200000. In both cases the id of the TimeZone is America/Los_Angeles.

REGRESSION. Last worked in version 1.3.1

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. run code snippet from description under jdk 1.4, 1.4.1-beta and 1.3.1

EXPECTED VERSUS ACTUAL BEHAVIOR :
offset should be -25200000 but is -28800000

REPRODUCIBILITY :
This bug can be reproduced always.

public class Test {

  public static void main(String[] args) {
    
    GregorianCalendar c = new GregorianCalendar(96,5,1);
    int offset = c.getTimeZone().getOffset(c.get(Calendar.ERA),

                                           c.get(Calendar.MONTH),
                                           c.get(Calendar.DAY_OF_MONTH),

                                           c.get(Calendar.MILLISECOND));

    System.out.println("offset " + offset);
