HarmonyOS 如何获取本地时区

获取系统时区可以使用：

systemDateTime.getTimezoneSync10+   getTimezoneSync(): string 

参考示例如下：

import { BusinessError } from '@kit.BasicServicesKit';

try {
  let timezone = systemDateTime.getTimezoneSync();
} catch (e) {
  let error = e as BusinessError;
  console.info(`Failed to get timezone. message: ${error.message}, code: ${error.code}`);
}
