Not all platforms implement GetTime(), but the SCT just assumes calls to
GetTime will be successful. If GetTime() doesn't return EFI_SUCCESS,
then the EFI_TIME value will be uninitialized data.
Fix by checking the GetTime() return code. If it doesn't return
EFI_SUCCESS, then use the traditional 1/1/1970 epoch so that the test
report at least looks sane, but it is obvious that we don't have a valid
timestamp.

I tried to apply your patch with 'git am --keep-cr'. This chunk has a
problem.
While all other lines in the file have CR LF line endings this very line
has only LF in EDK2 master. But your patch has CR LF for the line.
Did you use Windows and not Linux to create the patch?
I could apply your patch after removing the extraneous CR.
With your patch applied if GetTime() returns EFI_UNSUPPORTED, the test
log is not garbled anymore:
SetVariable_Conf:
Test Finished: 01/01/70 12:00a
Elapsed Time: 00 Days 00:00:00
If GetTime() is available:
SetVariable_Conf:
Test Finished: 08/01/20 01:52p
Elapsed Time: 00 Days 00:00:04
Except for the line-endings:

From what I can tell, that file already had inconsisten line endings. Most of the file is crlf, but the "#include "SctLib.h" line is lf only.

One issue here is that UEFI 2.8 spec language around allowing runtime services (like GetTime() ) to return EFI_UNSUPPORTED is a bit vague:
""
EFI_UNSUPPORTED
This call is not supported by this platform at the time the call is made. The platform should describe this runtime service as unsupported at runtime via an EFI_RT_PROPERTIES_TABLE configuration table.
""
The "at the time the call is made" language may be interpreted as the service is allowed to return EFI_UNSUPPORTED anytime (before or after ExitBootServices() ). But the next sentence (about declaring the unsupported at runtime) make it sounds like this is restricted to only being at runtime. While the use case makes sense, we may need some clarification in the UEFI spec language to make this clear. Otherwise, callers (like SCT) may assume the function is always supported.

The platform should describe this runtime service as unsupported at runtime via an EFI_RT_PROPERTIES_TABLE configuration table. > "" > > The "at the time the call is made" language may be interpreted as the service is allowed to return EFI_UNSUPPORTED anytime (before or after ExitBootServices() ). But the next sentence (about declaring the unsupported at runtime) make it sounds like this is restricted to only being at runtime. While the use case makes sense, we may need some clarification in the UEFI spec language to make this clear. Otherwise, callers (like SCT) may assume the function is always supported. Some systems do not have a real time clock. So these system have to return EFI_UNSUPPORTED before as well as after ExitBootServices(). Due to possible conflicts with the access by the operating system many systems with RTC will opt not to implement GetTime() at runtime but may implement GetTime() before ExitBootServices(). This is what we do in U-Boot. But of cause it is allowable to provide the service at all times if feasible. An implementation supplying GetTime() only after ExitBootServices() would not make much sense to me but is not explicitly forbidden by the spec. A clearer wording for the spec might be: "If the service is available at runtime or not, has to be marked in the EFI_RT_PROPROPERTIES_TABLE."
