HarmonyOS 使用华为公仓的dayjs，系统时区设置设置欧洲时区，转换成北京时间时丢失时间信息或者时间失效。

参考时间戳转换时间字符demo

let date = new Date(1710161336 * 1000);
const year = date.getFullYear();
const month = ("0" + (date.getMonth() + 1)).slice(-2);
const day = ("0" + date.getDate()).slice(-2);
const hours = ("0" + date.getHours()).slice(-2);
const minutes = ("0" + date.getMinutes()).slice(-2);
const seconds = ("0" + date.getSeconds()).slice(-2);
let formattedDate = `${year}-${month}-${day} ${hours}:${minutes}:${seconds}`
