 If you consider functions f(xyxt) - adding time to xyz,
  you are talking about the trajectories or orbits and you should not
  call them 'configurations' which imply a snapshot in time.  In
  case of fields I would say you deal with 'histories' - until somebody
  suggests a better word. Also - if u want to be really relativistic, it
  may not be enough to think about psi as scalar. Even Dirac eq. has more.
