`antd@2.0` 之后，时间类组件的 `value` 改为 `moment` 类型，所以在提交前需要预处理。

 en-US

After `antd@2.0`, the `value` of time-related components had been changed to `moment`. So, we need to pre-process those values.

````jsx
import { Form, DatePicker, TimePicker, Button } from 'parkball';

const FormItem = Form.Item;
const MonthPicker = DatePicker.MonthPicker;
const RangePicker = DatePicker.RangePicker;

class TimeRelatedForm extends React.Component {
  handleSubmit = (e) => {
    e.preventDefault();

    this.props.form.validateFields((err, fieldsValue) => {
      if (err) {
        return;
      }

      // Should format date value before submit.
      const rangeValue = fieldsValue['range-picker'];
      const rangeTimeValue = fieldsValue['range-time-picker'];
      const values = {
        ...fieldsValue,
        'date-picker': fieldsValue['date-picker'].format('YYYY-MM-DD'),
        'date-time-picker': fieldsValue['date-time-picker'].format('YYYY-MM-DD HH:mm:ss'),
        'month-picker': fieldsValue['month-picker'].format('YYYY-MM'),
        'range-picker': [rangeValue[0].format('YYYY-MM-DD'), rangeValue[1].format('YYYY-MM-DD')],
        'range-time-picker': [
          rangeTimeValue[0].format('YYYY-MM-DD HH:mm:ss'),
          rangeTimeValue[1].format('YYYY-MM-DD HH:mm:ss'),
        ],
        'time-picker': fieldsValue['time-picker'].format('HH:mm:ss'),
      };
      console.log('Received values of form: ', values);
    });
