1 /** @file 2 Real Time clock Architectural Protocol as defined in PI Specification VOLUME 2 DXE 3 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. 13 14 Copyright (c) 2006 - 2018, Intel Corporation.
