Abstract. A detailed list of postulates is formulated in an algebraic setting.
These postulates are sufficient to entail the standard time evolution
governed by the Schr\"odinger- or Dirac equation. They are also necessary
in a strong sense: Dropping any one of the postulates allows for other
types of time-evolution, as is demonstrated with examples. Some
philosophical remarks shall hint on possible further investigations.
