life cycle expires cookie time expired, but have not been cleaned browser cookie problem

Nodejs played today with a web service, using art-template template engine render the page where I set a cookie, set the expiration time to 10 seconds after the code is as follows:

var t = new Date();

var day = t.getSeconds() + 10;

t.setSeconds(day);

// time to failure is converted into a string

was TSTR = t.toString ();

if (document.cookie.length <= 0) {

     document.cookie = 'name=小明; expires=' + tStr;

}

 

But 10 seconds after the last cookie has not expired, you can also get to find for a long time had rendered the service side of the page, the cookie expiration time the comparison is made according to the time server

Server time:

 

Client time:

So the time to failure by services from time to set up, cookie can successfully fail, the browser is cleared.

Here the server time, I was in the print server.
