title: Prefill current date in Google Form with Google Apps Script
body: <p>I have a Google Form to a spreadsheet and I need a date field pre-filled with the current date. </p>
  
  <p>Something like an <code>"onOpen trigger"</code>, which updates the date field or a date field with now().</p>
  
  <p>Is this possible in Google Apps Script?</p>
