为什么我的MongoDB领域GraphQL端点返回这样的日期，以及如何在客户端中解析它

const dateString = "2022-01-01T12:00:00Z";
const date = new Date(dateString);
console.log(date);

import datetime

date_string = "2022-01-01T12:00:00Z"
date = datetime.datetime.fromisoformat(date_string)
print(date)

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;

String dateString = "2022-01-01T12:00:00Z";
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'");
try {
    Date date = format.parse(dateString);
    System.out.println(date);
} catch (ParseException e) {
    e.printStackTrace();
}
