[Scott, W Alan]

Thanks.  I passed this on to my user.  If necessary, I will poke either Jeff or Kitware.

    Alan,
    
    So in summary, yes it is possible to do this with the programmable filter. What you do is check the time to see if it equals the target time step. If so, save the array from the desired field in a global variable. Then on other time steps do the difference. 
    
    You may have noticed I'm not giving you code. This is because I am too lazy to spend the hour or so getting it to work.
