插入到数据库时，时间选择器格式发生更改

// 示例代码：前端时间选择器格式化
const selectedDateTime = new Date();
const formattedDateTime = selectedDateTime.toISOString().replace('T', ' ').substring(0, 19);
console.log(formattedDateTime); // 输出：YYYY-MM-DD HH:MM:SS

// 示例代码：后端处理日期时间格式
const express = require('express');
const app = express();
app.use(express.json());

app.post('/insert', (req, res) => {
    const { dateTime } = req.body;
    const formattedDateTime = new Date(dateTime).toISOString().replace('T', ' ').substring(0, 19);
    // 插入数据库
    console.log(formattedDateTime); // 输出：YYYY-MM-DD HH:MM:SS
    res.send('Inserted successfully');
});

app.listen(3000, () => {
    console.log('Server is running on port 3000');
});

CREATE TABLE example_table (
    id INT AUTO_INCREMENT PRIMARY KEY,
    event_datetime DATETIME NOT NULL
