在映射函数过程中，在React中将Unix时间戳转换为日期

const unixTimestamp = 1631234567; // Unix时间戳
const javascriptTimestamp = unixTimestamp * 1000; // 转换为JavaScript时间戳

const date = new Date(javascriptTimestamp); // 创建日期对象

const year = date.getFullYear(); // 获取年份
const month = date.getMonth() + 1; // 获取月份（注意月份从0开始，需要加1）
const day = date.getDate(); // 获取日期
const hours = date.getHours(); // 获取小时
const minutes = date.getMinutes(); // 获取分钟
const seconds = date.getSeconds(); // 获取秒数

const dateString = `${year}-${month}-${day} ${hours}:${minutes}:${seconds}`;

function convertUnixTimestampToDateString(unixTimestamp) {
  const javascriptTimestamp = unixTimestamp * 1000;
  const date = new Date(javascriptTimestamp);
  const year = date.getFullYear();
  const month = date.getMonth() + 1;
  const day = date.getDate();
  const hours = date.getHours();
  const minutes = date.getMinutes();
  const seconds = date.getSeconds();
  const dateString = `${year}-${month}-${day} ${hours}:${minutes}:${seconds}`;
  return dateString;
}
