Initially the textbox is with this value [Tue Mar 06 05:00:00 UTC 2012] .
but when i click on text box n select the date . date picker gives the second date in textbox Wed May 09 12:00:00 UTC+2 2012. The first one may be illegalArgument as it is set by me. but the second one is set by the date picker.

This should work

import com.google.gwt.i18n.client.DateTimeFormat; 

DatePicker datePicker=new DatePicker();  // Have to make final to use in inner method


timebx.addClickHandler(new ClickHandler() {

        public void onClick(ClickEvent event) {
            // TODO Auto-generated method stub
            String strDate = timebx.getText();
            DateTimeFormat format = DateTimeFormat.getFormat("yyyy-MM-dd");
            try {  
              Date selDate = (Date)format.parse(strDate); 
              datePicker.setValue(selDate, true);
            } catch(Exception pe){
             // setting current date
             datePicker.setValue(new Date(), true);
            }

            int x=timebx.getAbsoluteLeft();
            int y=timebx.getAbsoluteTop();
            popupPanel.setPopupPosition(x, y+20);
            popupPanel.show();
        }
    });
