使用Material-UI KeyboardTimePicker，如何在不更改日期的情况下更改时间？

import React, { useState } from 'react';
import { KeyboardTimePicker, MuiPickersUtilsProvider } from '@material-ui/pickers';
import DateFnsUtils from '@date-io/date-fns';

const [selectedTime, setSelectedTime] = useState(new Date());

const handleTimeChange = (time) => {
  setSelectedTime(time);
};

<MuiPickersUtilsProvider utils={DateFnsUtils}>
  <KeyboardTimePicker
    value={selectedTime}
    onChange={handleTimeChange}
    keyboardIcon={<YourKeyboardIcon />}
  />
</MuiPickersUtilsProvider>
