A jQuery clock where I can set the initial time and then let it run client side

I'd like to set the time at the top of my site and have it constantly update itself, only client side.

So on the initial page loa开发者_如何转开发d, I'd give it the server time:

[HttpPost]
public ActionResult GetTime()
{
    return Content(@DateTime.Now.AddHours(3).ToString("HH:mm"));
    //Returns something like: "20:05"
}

Then I'd like the client to just start running a clock starting from the time I've given it.

So when a user loads the page, he recieves 20:05 and without regarding his own local time, I'd like that clock to move forward in a regular fashion. 20:06, 20:07, etc.

Is there something like this available for jQuery?

Here's an example of incrementing a number on a page by 1 every second: http://jsfiddle.net/ct3VW/

Is that enough for you to work with?
