  status.text = "Date and time: #{time.to_s("%F %T")}"
end

form = UIng::Form.new(padded: true)
form.append("Date:", date_picker)
form.append("Time:", time_picker)
form.append("Date and time:", date_time_picker)

window.child = box
window.show

UIng.main
UIng.uninit

Usage notes

• Construct it with :date, :time, or :date_time. The typed UIng::DateTimePicker::Type values are also accepted.
• Values are local wall-clock fields; assigning a Time does not preserve its original zone or instant.
