// .NAME vtkTemporalSnapToTimeStep - modify the time range/steps of temporal data
// .SECTION Description
// vtkTemporalSnapToTimeStep modify the time range or time steps of
// the data without changing the data itself. The data is not resampled
// by this filter, only the information accompanying the data is modified.
// .SECTION Thanks
// John Bidiscombe of CSCS - Swiss National Supercomputing Centre
// for creating and contributing this class.
// For related material, please refer to :
