title: Measure time to fill section - google forms
body: <p>I'm trying to use google forms for a research questionnaire.
  for some of the sections I want to automatically measure the time takes the user to fill.</p>
  
  <p>there is no option like this in google forms.
  I've tried to copy the form source, and fill the time with javascript but it didn't worked (Cross-Origin issue) - Didn't succeed to host the copied form.</p>
  
  <p>How it can be done - how can I measure the time that took to answer a form?
  is there an other forms-like service that allow measuring time per question?</p>
