title: How can I have the total time Psychopy
body: <p>I made an experimentation on Psychopy. I have Intructions, 10 differents routines and then msg end.</p>
  
  <p>I am able to have all the time it took for each routine, but I will like to have the total time of my 10 routines without having to calculate it my self in my csv file at the end.</p>
  
  <p>Code for having my duration of each trial. I putted this line in each routine.</p>
  
  <pre><code>thisExp.addData('trial_duration1', t)
  </code></pre>
  
  <p>I tried to create a variable total and adding all the trial_duration, but my column was empty in the csv file at the end.</p>
  
  <p>Thanks!!</p>
