IBM Portal / WCM Forum

Hi All,
I am working in lotus Quickr and got to know the components in it like Wikis, Blogs, Ask the expert, Suggestion scheme and Discussion forum use WCM as their repository.
I am trying to get the latest entries(say one week older) in the above mentioned components, which means I should use the WCM API to get the content. Please correct me if I am wrong here.
I have used the WCM api's  workspace.findContentModifiedSince(Date) method to get the entries, but this approach didn't provide the expected result. Below is the code snippet and the output that i get
when iterating through the DocumentIdIterator.
Please provide me your valuable suggestion on get the content from WCM.

private void getWCMComponentsData(PortletRequest request, PortletResponse response){
        Workspace  workspace = WCM_API.getRepository().getWorkspace(request.getUserPrincipal());
        workspace.useLiveAccess(true);
        Calendar CALENDAR = Calendar.getInstance();
        CALENDAR.add(Calendar.DAY_OF_YEAR, -1000);
        System.out.println(" test for date : "+CALENDAR.getTime());
        DocumentIdIterator docIdItr = workspace.findContentModifiedSince(CALENDAR.getTime());
        //System.out.println("test for docidItr : "+docIdItr.nextId().getId());
        ArrayList whatsNewAList = new ArrayList();
        while(docIdItr.hasNext()){
            DocumentId docIdObj=  docIdItr.nextId();
            Document docObj = workspace.getById(docIdObj);

                System.out.println("TItle "+docObj.getTitle()+" ModifiedDate: "+docObj.getModifiedDate());

            whatsNewAList.add("WCM::- "+docObj.getTitle()+" -- "+docObj.getModifiedDate());
        } }

Output of the above code

    Title                 ModifiedDate
