Rich: calendar problem when automatically adjust clock for daylight saving

Question

Hello, I'm in trouble when the option to automatically adjust clock for daylight saving time is marked. My locale is pt_BR, and when I try to select the day it simply returns to 17.10.2010 on 16.10.2010 took the test in the following component and realized that the same problem occurs when the Windows clock option is selected .
http://livedemo.exadel.com/richfaces-demo/richfaces/calendar.jsf?tab=usage&cid=15374785
I also noticed that this problem occurs in all components of the JSF schedule, no matter what the distribution
http://www.primefaces.org:8080/prime-showcase/ui/calendarDisplay.jsf
Question is, how to make the jsf solve this problem without having to uncheck the Windows clock?
See below for the following attempts to try to fix the problem:
faces-config.xml file
    <locale-config>
         <default-locale> en </ default-locale>
         <supported-locale> en_US </ supported-locale>
         <supported-locale> of </ supported-locale>
         <supported-locale> fr </ supported-locale>
        <supported-locale> es </ supported-locale>
        <default-time-zone-id> Brazil / East </ default-time-zone-id>
    </locale-config>
{code}
Created file DateTimeZoneConverter
{code:java}
import java.util.SimpleTimeZone;
import javax.faces.convert.DateTimeConverter;
public class extends DateTimeZoneConverter DateTimeConverter {
     public DateTimeZoneConverter () {
        super ();
        SimpleTimeZone stz = new SimpleTimeZone (7200000, "Brazil/East");
        this.setTimeZone (stz);
{code}
In the example above I'm forcing the useDaylight is false.
In component:
{code:java}
<rich:calendar id = "periodoVigencia" enableManualInput = "true" datePattern = "dd / MM / yyyy" inputSize = "10"
           value = "# () contratoMBeanList.criteria.dataInicioVigencia"
           label = "# (msg ['contrato.consultarContrato.field.periodovigencia.label'])">
           <f:convertDateTime pattern="dd/MM/yyyy" type="date" dateStyle="short" timeZone="GMT-3"/>
</rich:calendar>
{code}
and in the web.xml file
{code:java}
<context-param>
     <param-name> timezone </ param-name>
      <param-value> GMT-3 </ param-value>
</context-param>
{code}
But nothing worked. And now what do I do? How to fix this problem, there are some more configuration to be done? Help, please!
P.S.:Apologize for my english, I'm Brazilian.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   

Answer 1

Like I said, were attempts to resolve the error.
OK, now how to solve this problem? Try the test in your area by selecting the day that DST occurs, you will see what will happen the same problem (to select the day that DST occurs on the screen will return one day less), do the test with the demos that I put in the first post, rich: calendar and prime: calendar.
I do not know if it helps, but I noticed the firebug firefox debugging, it does not matter the way you change the locale or timezone, as the current date from the calendar javascript will always be the standard of the machine running the component.
