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.
