in ntexapi.h the structures _SYSTEM_QUERY_TIME_ADJUST_INFORMATION_PRECISE and _SYSTEM_SET_TIME_ADJUST_INFORMATION_PRECISE are defined but, it is not clear what API uses them.

from a bit of research, I am _guessing_ that they are used by NtQuerySystemInformation and NtSetSystemInformation respectively when the system information class is set to SystemTimeAdjustmentInformation

I would like to have confirmation as to whether this guess is correct or incorrect and, if incorrect which APIs use those structures.

Thank you.

They're used with this infoclass from memory.
