title: Adding Timecodes in Excel
body: <p>I have about 140 cells (they are in a vertical column) containing Timecodes in the Format hh:mm:ss:ff. 
  There are 24 Frames per second. 
  I would like to add them, so I have a total duration of all extracts.
  Can anyone tell me how I could do that in Micosoft Excel?
  Any help is greatly appreciated, since I am literally clueless...Thanks so much in advance!!</p>
