如何在react native中基于位置计算时间

import React, { useEffect, useState } from 'react';
import { View, Text } from 'react-native';
import Geolocation from '@react-native-community/geolocation';
import moment from 'moment-timezone';

const App = () => {
  const [currentTime, setCurrentTime] = useState('');

  useEffect(() => {
    // 获取设备当前位置信息
    Geolocation.getCurrentPosition(
      position => {
        const { latitude, longitude } = position.coords;
        // 根据经纬度获取时区
        const timezone = moment.tz.guess(latitude, longitude);
        // 根据时区计算当前时间
        const currentTime = moment().tz(timezone).format('YYYY-MM-DD HH:mm:ss');
        setCurrentTime(currentTime);
      },
      error => {
        console.log(error);
      }
    );
  }, []);

  return (
    <View>
      <Text>当前时间：{currentTime}</Text>
    </View>
  );
};

export default App;
