Hi @sp13test ,

If the CreateDate is a date column, try to modify as below:

            var oListItem = list.addItem(itemCreateInfo);  
            const timeElapsed = Date.now();  
            const today = new Date(timeElapsed);  
            oListItem.set_item('CreateDate', today);  
            oListItem.set_item('Title', Date.now().toString());   
            oListItem.update();  

Thanks
Best Regards
