Hi guys,

I want to fetch client's machine date & time.

I have used javascript to do so,

code:

XML

var currentTime = new Date();
var fulldate = currentTime.getFullYear()
     + '-' + currentTime.getMonth() + 1
     + '-' + currentTime.getDate()
     + ' ' + currentTime.getHours()
     + ':' + currentTime.getMinutes()
     + ':' + currentTime.getSeconds()
     + ':' + currentTime.getMilliseconds();

    <% Session["CDATE"] = "'" + fulldate + "'" %>

But, unfortunately sessions = "fulldate", like as string, where as i'm providing the variable name.

Plz suggest me what to do...

thanks

What you are doing won't work because your fulldate variable is initialized client side but Session ["CDATE"] is assigned server side.

Create a page that places your fulldate either in the url as a query string or in a cookie. Then redirect your page to another that gets the date value from the query string or cookie and then assign it to the session cache.

The <% %> notation can be used to embed server side code into the final rendered client side page.
It can not be work on the way around, as the content of <% %> parsed while still on the server.
If you want to get the client's time (time-zone) from the client you can do it only after postback. Read this article: http://www.prideparrot.com/blog/archive/2011/9/how_to_display_dates_and_times_in_clients_timezone[^]
An other option is to use some 3rd party to investigate the IP and decide to what timezone client belongs...

You can read the value of session at client side but can't initialized/write session at client side as it is a server object. Please use HiddenField to save the date of client system as shown below in example.

JavaScript

// Write this javascript code on <Head> tag of page and call it on window's load. 

 <script type="text/javascript">
        window.onload = function () {
            var currentTime = new Date();
            var fulldate = currentTime.getFullYear()
// here converting the month number into integer and then adding 1 to it. 
     + '-' + (parseInt(currentTime.getMonth()) + 1)
     + '-' + currentTime.getDate()
     + ' ' + currentTime.getHours()
     + ':' + currentTime.getMinutes()
     + ':' + currentTime.getSeconds()
     + ':' + currentTime.getMilliseconds();

// Save date in hidden field..
            document.getElementById('<%=hdnDate.ClientID%>').value = fulldate;
        }

I hope this solution will help you.. :)
    </script>

// Declaration of controls in <Body> tag of page..

ASP.NET

<asp:hiddenfield id="hdnDate" runat="server" xmlns:asp="#unknown" />
        <br />
        <br />
<asp:button id="btnGetDate" runat="server" text="Button" onclick="btnGetDate_Click" xmlns:asp="#unknown" />

// On Button Click, You can access client date at server side with help of hidden field..

C#

protected void btnGetDate_Click(object sender, EventArgs e)
   {
       Response.Write(hdnDate.Value);
   }
