addClass with Fade with mouse hover

addClass with Fade with mouse hover

Hello,
I´m trying to use the addClass with Fade in the event with mouse hover.
It works, but if I put a fade with 1 second, and the mouse in/out are less than 1 second, it did not work.
This is the code:
  $(document).ready(function(){ 
        $("#ultimos_jobs_1").hover(
        function(){
            $("#ultimos_jobs_1").addClass("tabela_td_ultimos_jobs_roolover", 1000);
        },
        function(){
            $("#ultimos_jobs_1").removeClass("tabela_td_ultimos_jobs_roolover", 1000);
        });       
  });
What should I do?
