use12Hours does not work on TimePickerPanel

[ghost]

The code listed below results in the error: "Uncaught TypeError: Cannot read property 'match' of undefined" Can we use use12Hours prop on the TimePIckerPanel?

<TimePickerPanel showSecond={false} use12Hours={true} defaultValue={moment('00:00', 'HH:mm a')} />

You must also supply a format.
