HarmonyOS systemDateTime能够获取更多时区信息

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());
