JSF - How to show the client side local timezone date and time in the XHTML

Question

My issue is related to this topic

My requirement is,I need to show the client side date in the UI and I tried many options none of them give results.

The code below shows the correct date which I changed in the machine.But when I deploy the same code in the server which is located in US, the date is not getting changed. It shows the server date and I need to show the user local timezone date wherever the user is accessing the application.
For no reason, I assigned the value of the variable #{sessionScope.TIMEZONE} ="GMT".

Here is my code given in XHTML

<h:outputText
                            value="Current Login Date: #{sessionScope.LOGINTIME}"
                            style="font-weight:normal;white-space:nowrap">
                            <f:convertDateTime type="both" dateStyle="default"
                                timeStyle="default" timeZone="#{sessionScope.TIMEZONE}" />
                        </h:outputText>

Like I said I need to show the local timezone date in the UI.Really appreciate your help.

I achieved by this using the below code in XHTML.

<h:outputText id="loggedDt5"
                            style="font-weight:normal;white-space:nowrap" />
                        <SCRIPT type="text/javascript">
                            var now = new Date();
                            document.getElementById('headerform:loggedDt5').innerHTML = 'Current Login Date:'+(now
                                    .getMonth() + 1)
                                    + "/"
                                    + now.getDate()
                                    + "/"
                                    + now.getFullYear();
                        </SCRIPT>

Since it is a client machine from where you need the it is more sensible to use JavaScript to get the required date and display it in the local timezone format.

var d = new Date();
var localTime = d.getTime(); 

var offset = d.getTimezoneOffset();

The documentation for getTimezoneOffset.

Using the offset you can convert to the local timezone. A very good tutorial regarding he same can be accessed at http://www.techrepublic.com/article/convert-the-local-time-to-another-time-zone-with-this-javascript/
