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