DateTimeFormat issue

[Freddy Boucher]

Hi,

Can someone help me to understand why this test fails (I'm using GWT 2.7.0):

package com.threatmetrix.ccc.portal.widgets.barchart.client;

import com.google.gwt.i18n.client.DateTimeFormat;
import com.google.gwt.i18n.client.TimeZone;
import com.google.gwtmockito.GwtMockitoTestRunner;
import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;

import java.util.Date;

@RunWith(GwtMockitoTestRunner.class)
public class DateTimeTest {
    @Test
    public void working() {
        Date date = new Date(1457395200000l);
        DateTimeFormat format = DateTimeFormat.getFormat(DateTimeFormat.PredefinedFormat.ISO_8601);
        String formattedDate = format.format(date, TimeZone.createTimeZone(0));

        Assert.assertEquals("2016-03-08T00:00:00.000+00:00", formattedDate);
        Assert.assertEquals(date, format.parse(formattedDate));
    }


    @Test
    public void notWorking() {
        Date date = new Date(1459639080000l);
        DateTimeFormat format = DateTimeFormat.getFormat(DateTimeFormat.PredefinedFormat.ISO_8601);
        String formattedDate = format.format(date, TimeZone.createTimeZone(0));

        Assert.assertEquals("2016-04-03T23:18:00.000+00:00", formattedDate);
        Assert.assertEquals(date, format.parse(formattedDate));
    }
}

Results:

• DateTimeTest#working(): OK
• DateTimeTest#notWorking(): there is a difference of 1 day between the Expected and the Actual date

Log:

java.lang.AssertionError: 

Expected :Sun Apr 03 09:18:00 AEST 2016

Actual   :Mon Apr 04 09:18:00 AEST 2016

Looks to me like this bug:

which was (coincidentally?) mentioned today here:
