Is it possible to test if a javascript cookie has expired using?

I need to do a few thing conditionally and two of those conditions are overlapping for which if it could be tested whether a cookie has expired then it will be easier for me to get things done.

I am using jquery-1.5.js and jquery.cookies.js plugin.

Thanks.

CODE

var jq = jQuery.noConflict();

jq(document).ready(function () {



    var timeStart, timeSubmit, timeLeft;

    timeSubmit = 5 * 60 * 1000;

    timeStart = jaaulde.utils.cookies.get(_watchman);

    try {

        if(jaaulde.utils.cookies.test()) {

            throw err1;

        }

        else if(hasCookieExpired) {

            throw err2;

        }

        else if(!timeStart) {

            jaaulde.utils.cookies.set(_watchman, String(new Date().getTime()), {path: '/path', expiresAt: new Date((new Date().getTime() + timeSubmit))});

            timeLeft = timeSubmit - (new Date().getTime() - Number(jaaulde.utils.cookies.get(_watchman)));

            timeCheck();

        }

        else {

            timeLeft = timeSubmit - (new Date().getTime() - Number(jaaulde.utils.cookies.get(_tts)));         



            timeCheck();

        }



    } catch(err) {

        //handle errors

    }



    function timeCheck() {

            if(timeLeft <= 0) {

                triggerSubmit();

            }

            else {

                setTimeout(triggerSubmit, timeLeft);    

                setInterval(showTimeLeft, 1000);

            }       

    }



    function triggerSubmit() {

        //submit it

    }



    function showTimeLeft() {

        //do something

    }



});
