NTRTL.H

The public symbol file NTKRPAMP.PDB for the original release of Windows 10 tells that the kernel is built with the NTRTL.H header at

d:\th.public.fre\internal\minwin\priv_sdk\inc

and draws from it the following type definition:

Line Number Type
2211 struct _RTL_TIME_ZONE_INFORMATION

The header NTRTL.H is not known in any Device Driver Kit (DDK) or Windows Driver Kit (WDK).

For the record, here are the very many more types that Microsoft’s freely published URLMON.PDB reveals were accessible to the source code for URLMON.DLL from including this same NTRTL.H when building Internet Explorer for the original release of Windows 10:
