HarmonyOS 获取时区

可以使用new Date()示例参考如下：

let date: Date = new Date();
console.info(`date.toString() res : ` + date.toString());
console.info(`date.toDateString() res: ` + date.toDateString());
console.info(`date.toTimeString() res: ` + date.toTimeString());
console.info(`date.toLocaleString() res: ` + date.toLocaleString());
console.info(`date.toLocaleDateString() res: ` + date.toLocaleDateString());
console.info(`date.getFullYear() res: ` + date.getFullYear());
console.info(`date.getUTCFullYear() res: ` + date.getUTCFullYear());
console.info(`date.getMonth() res: ` + date.getMonth());
console.info(`date.getUTCDay() res: ` + date.getUTCDay());
console.info(`date.getDay() res: ` + date.getDay());
//输出结果如下所示
date.toDateString() res: Wed Nov 15 2023
date.toTimeString() res: 17:40:43 GMT+0800
date.toLocaleString() res: 11/15/2023, 5:40:43 PM
date.toLocaleDateString() res: 11/15/2023
date.getFullYear() res: 2023
date.getUTCFullYear() res: 2023
date.getMonth() res: 10
date.getUTCDay() res: 3
date.getDay() res: 3
