Set the value of this time object to the specified `hour`, and the optionally specified `minute`, `second`, `millisecond`, and `microsecond`, if they would comprise a valid `Time` value (see `isValid`). Return 0 on success, and a non‐zero value (with no effect) otherwise. Unspecified arguments default to 0.
