var ts;

_spBodyOnLoadFunctionNames.push("TimesheetMain");function TimesheetMain() {

}function TimesheetExtension() {var _grid;var _satellite;if (window.PJ == null || PJ.AddGridSatelliteInitializationNotifier == null) {return;
  }

  PJ.AddGridSatelliteInitializationNotifier(
    function (satellite) {if (PJ.TimesheetSatellite != null) {
        satellite = PJ._NotifySatelliteInitComplete.arguments[0];
        _satellite = satellite;

        _grid = satellite.GetJsGridControlInstance();
        _grid.AttachEvent(SP.JsGrid.EventType.OnRightClick, RightClick);
