18 * @short Composite spinbox for specifying a time step.
19 * This composite widget consists of a TimeSpinBox (a QSpinBox), coupled with a
20 * TimeUnitBox (a second pair of up/down buttons).
21 * The second set of buttons makes larger steps through the 82 possible
22 * time-step values, skipping to the next even unit of time.
