+ * - `empty` - If true, the empty select option is shown. If a string,
+ *   that string is displayed as the empty element.
+ * - `round` - Set to `up` or `down` if you want to force rounding in either direction. Defaults to null.
+ * - `value` | `default` The default value to be used by the input. A value in `$this->data`
+ *   matching the field name will override this value. If no default is provided `time()` will be used.
+ * - `timeFormat` The time format to use, either 12 or 24.
+ * - `second` Set to true to enable seconds drop down.

+ * To control the order of inputs, and any elements/content between the inputs you
