value 和 onChange 需要配合使用。

````jsx
import { TimePicker } from 'antd';

const Test = React.createClass({
  getInitialState() {
    return {
      value: null,
    };
  },
  onChange(time) {
    console.log(time);
    this.setState({ value: time });
  },
  render() {
    return <TimePicker value={this.state.value} onChange={this.onChange} />;
  }
});

ReactDOM.render(<Test />, mountNode);
