# Time Picker

A [dialog picker](https://material.google.com/components/pickers.html#pickers-time-pickers) is used to select a single time (hours:minutes). The selected time is indicated by the filled circle at the end of the clock hand.

<!-- example -->
```jsx
import TimePicker from 'react-toolbox/lib/time_picker';

let time = new Date();
time.setHours(17);
time.setMinutes(28);

class TimePickerTest extends React.Component {
  state = {time};

  handleChange = (time) => {
    this.setState({time});
  };

  render () {
    return (
      <TimePicker
        label='Finishing time'
        onChange={this.handleChange}
        value={this.state.time}
      />
    );
  }
}
```

If you want to provide a theme via context, the component key is `RTTimePicker`.
