Compare TIME_SPENT value

Hi , 

Im trying to create a script based condition that will check if task   
is in status complete for defect type and TIME_SPENT is not zero.   
I can find the way to compare the value of TIME_SPENT.                  
                                                                        
This is my java script:                                                 
dojo.provide("org.example.workitems.providers.                          
CheckTimeRemainingForTask");                                            
dojo.require("com.ibm.team.workitem.api.common.WorkItemAttributes");    
                                                                        
(function() {                                                           
var WorkItemAttributes= com.ibm.team.workitem.api.common.               
WorkItemAttributes;                                                     
var scriptname = "CheckTimeRemainingForTask";                           
var doDebug = true;                                                     
                                                                        
dojo.declare("org.example.workitems.providers.                          
CheckTimeRemainingForTask", null, {                                     
    matches: function(workItem, configuration) {                        
var type = workItem.getValue(WorkItemAttributes.TYPE);                
var state = workItem.getValue(WorkItemAttributes.STATE);//3 =        
complete                                                                
var timespent = workItem.getValue(WorkItemAttributes.TIME_SPENT);     
                                                                        
if ((type === "task") &&                                              
    (state === "3") &&                                                
(timespent > 0 )){                                                   
debug("type is task and state is complete and timespent is not zero  
!!!!!");                                                                
}                                                                     
                                                                        
return ((type === "task") &&                                          
    (state === "3") &&                                                
(timespent > 0 ));                                                   
                                                                        
                                                                        
function debug(display){                                              
if(doDebug){                                                         
console.log(scriptname+ "-" + display);                             
}                                                                    
}                                                                      
}                                                                      
});                                                                     
})();                                                                   
                                                                        
The timespent type is number (I checked with the command typeof).       
The value of timespent when I print it to the console is: 39600000.     
I tried to compare with the operators > 0 , == 0 , convert to       
string and compare to 39600000 but nothing works.                     
                                                                        
Can someone help me with this issue ?                                   
                                                                        
BR,
