Good point.  I have added the following method to
  public int getCurrent()
It returns the ordinal step number of the current
animation step.  You can get the Time value as
  int current = animation_control.getCurrent();
  float[][] values
    animation_control.getSet().indexToValue(new int[] {current});
  float time_value = values[0][0];
Note that AnimationControl.getSet() returns the
(1-D) Set of samples of Time (or whatever RealType
is mapped to Animation) associated with animation
