/** @file
Real Time clock Architectural Protocol as defined in PI Specification VOLUME 2 DXE
This code abstracts time and data functions. Used to provide
Time and date related EFI runtime services.
The GetTime (), SetTime (), GetWakeupTime (), and SetWakeupTime () UEFI 2.0
services are added to the EFI system table and the
EFI_REAL_TIME_CLOCK_ARCH_PROTOCOL_GUID protocol is registered with a NULL
pointer.
No CRC of the EFI system table is required, as it is done in the DXE core.
