| 4 | This code abstracts time and data functions. Used to provide
|
|---|
| 5 | Time and date related EFI runtime services.
|
|---|
| 6 |
|
|---|
| 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
|
|---|
| 10 | pointer.
|
|---|
| 11 |
|
|---|
| 12 | No CRC of the EFI system table is required, since that is done in the DXE core.
