  <p>I have been trying to add up the datetime but I always fail:</p>
  
  <pre><code>finput = open("./Test.csv", "r")
  while 1:
    line = finput.readline()
    if not line:
      break
    else:
      user = line.split(delim)[0]
      direction = line.split(delim)[1]
      duration = line.split(delim)[2]
  
      durationz = 0:00:00
      for k in duration:
        durationz += k
  </code></pre>
  
  <p>Also:
        is there a specific way to declare a time value?  </p>
