$('#map_canvas').mouseover(function(e){
var offset = $('#map_canvas').offset();

$('#map_canvas').mouseover(function(e){
    var offset = $('#map_canvas').offset(); 
    var x = e.pageX - offset.left;
    var y = e.pageY - offset.top;

    console.log('X: '+x+' Y: '+y); //you want this

    //console.log(offset.top+'  '+offset.left); //offset of 'realtiveDiv'
    //console.log(e.pageX +'  '+e.pageY); // mouse position absolute
});

Update:
if offset.top and offset.left log (0, 0), it means that the element whose offset you are logging, starts at (0, 0). In other words, the element is at the top left corner of the screen.
