+/** @file\r
+ Real Time clock Architectural Protocol as defined in DXE CIS\r
+\r
+ This code abstracts time and data functions. Used to provide\r
+ Time and date related EFI runtime services.\r
+\r
+ The GetTime (), SetTime (), GetWakeupTime (), and SetWakeupTime () EFI 1.0\r
+ services are added to the EFI system table and the \r
+ EFI_REAL_TIME_CLOCK_ARCH_PROTOCOL_GUID protocol is registered with a NULL \r
+ pointer.\r
+\r
+ No CRC of the EFI system table is required, as it is done in the DXE core.\r
