javascript date to string

Here is what I need to do.

Get Date, convert to string and pass it over to a third party utility. The response from the library will have date in string format as I passed it. So, I need to convert the date to string like 20110506105524 (YYYYMMDDHHMMSS)

function printDate() {
    var temp = new Date();
    var dateStr = temp.getFullYear().toString() + 
                  temp.getMonth().toString() + 
                  temp.getDate().toString() +
                  temp.getHours().toString() + 
                  temp.getMinutes().toString() + 
                  temp.getSeconds().toString();

    debug (dateStr );
}

The problem with above is that for months 1-9, it prints one digit. How can I change it to print exactly 2 digits for month, date ...
