    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, since that is done in the DXE core.
