      public static interface TemporalFunction.Hour
      extends TemporalFunction<Integer>, QueryFunction.PropertyQueryFunction<Integer,Object>, NumericQueryExpression<Integer>

  A function to extract the hour part of a temporal data type. The 24-hour clock is used.

  The result type is always an `Integer` and the hour range index is between 0 and 23.
