:mrdocs:

Return `true` if the specified `hour`, and the optionally specified `minute`, `second`, `millisecond`, and `microsecond`, represent a valid `Time` value, and `false` otherwise. Unspecified arguments default to 0. The `hour`, `minute`, `second`, `millisecond`, and `microsecond` attributes comprise a valid `Time` value if `0 <= hour < 24`, `0 <= minute < 60`, `0 <= second < 60`, `0 <= millisecond < 1000`, and `0 <= microsecond < 1000`. Additionally, 24:00:00.000000 also represents a valid `Time` value.
