  16 Abstract:
  17
  18   Real Time clock Architectural Protocol as defined in Tiano
  19
  20   This code abstracts time and data functions. Used to provide
  21   Time and date related EFI runtime services.
  22
  23   The GetTime (), SetTime (), GetWakeupTime (), and SetWakeupTime () EFI 1.0
  24   services are added to the EFI system table and the
  25   EFI_REAL_TIME_CLOCK_ARCH_PROTOCOL_GUID protocol is registered with a NULL
  26   pointer.
  27
  28   No CRC of the EFI system table is required, as it is done in the DXE core.
