  * The Real Time Clock (RTC) operation is verified by this test.
  * The following features are verified:
+ *   o) RTC Power Fault
+ *	This is verified by analyzing the rtc_get() return status.
  *   o) Time uniformity
  *      This is verified by reading RTC in polling within
  *      a short period of time.
