To pass the additional parameter to the event function pass an array of  key value, as the second parameter to the bind event

bind('click', { message: time }, onClick); 

e.g 

{ message: time }

and access it in the function 

using event(function parameter).data.message(key)

<div id="div1" style="border: 1px solid black; width: 100px; height: 100px">
click me
</div>
 
<script type="text/javascript">         
    function onClick(event)        
    {            
        alert(event.data.message);        
    }  
       
    var time = "loaded at:" + new Date().toString();        
    $("div.#div1").bind('click', { message: time }, onClick);    
</script>
