You need to have a date/time field to store the date and the code below

 

<script>
  var chk= document.getElementById("CheckboxID");
  document.getElementById('caspioform').onsubmit = function(){
  if (chk.checked){
  document.getElementById('Date Field ID').value = "[@cbTimeStamp]"; 
  } else {
  document.getElementById('Date Field ID').value = "";
  }
  }
</script>
