/*
* 测试 RTC 的时间功能与闹钟功能，在RTCd的寄存器中保存的时间信息
* 是以 UTC 时间保存的，要使用本地时间需要配置时区，当前配置的时
* 区是东八区，即北京时间（CST）
*
* 在设置时间日期时使用 set_time() 与 set_date() 接口，设置的时
* 间这两个接口内部会做时区转换
*
* 测试说明：
* 基于庐山派开发板测试（01Studio 的开发板无法使用硬件RTC，
* 因为没有接 int0/4 的上拉）
* RTC 为 K230 自带的 RTC
* RTC 的时钟源为外部 32.768KHz 晶振
* 在测试终端运行该测试后，会分别进行 test_rtc_set(),
* test_rtc_alarm() 与 test_rtc_interface() 三个测试。
* 其中 test_rtc_set() 会通过 set_time() 与 set_date() 设置时间，
* 注意设置的时间需要为本地时间，内部会转换成 UTC 时间，然后调用
* drv_rtc.c 内的接口设置到 RTC 寄存器中；
* test_rtc_alarm() 会设置一个 5 秒后的闹钟时间，并注册一个闹钟
* 中断回调函数，同样用户设置的闹钟时间为本地时间，内部会转换成UTC
* 时间然后保存进 RTC 中；
* test_rtc_interface() 会测试读写 RTC 的接口，写 RTC 时同样需要
* 提供本地时间，读出来后需要转换成本地时间（如果有需要）。
