 * SECTION:hildon-time-button
 * @Short_Description: Button displaying and allowing selection of a time.
 * @See_Also: #HildonPickerButton, #HildonDateButton
 *
 * #HildonTimeButton is a widget that shows a text label and a time, and allows
 * the user to select a different time. Visually, it's a button that, once clicked,
 * presents a #HildonPickerDialog containing a #HildonTimeSelector. Once the user selects
 * a different time from the selector, this will be shown in the button.
