      """
      Returns a new Index with the same type as the input `index`, containing the values between `start`
      and `end` included. If start and end are not in the index, the closest values are used instead.
      The start and end values can be either integers (in which case they are interpreted as indices),
      or pd.Timestamps (in which case they are interpreted as actual timestamps).
  
  
      Parameters
      ----------
      index
          The index to slice.
      start
          The start of the returned index.
      end
          The end of the returned index.
  
      Returns
      -------
      Union[pd.RangeIndex, pd.DatetimeIndex]
          A new index with the same type as the input `index`, but with only the values between `start` and `end`
          included.
