While I’m working on NDIS filter driver development, and I have to obtain current system time. It is possible to include time.h in precomp.h but I cannot use time(), ctime() and other similar functions in my main functions since it will cause a link error:
error LNK2019: unresolved extern symbol __imp__localtime referenced in function _FilterSendNetBufferLists@16
Could anyone told me which functions are available here in kernel to obtain current system time? Or how can I solve this problem?
Thanks.
KeQuerySystemTime to ge the system time, ExSystemTimeToLocalTime to convert it to local time

I think they are just absent in the kernel.
KeQuerySystemTime is one of the solutions.
