I wonder if native works well if time difference doesn't fit into ULONG, 
did you check that? If it doesn't - the simplest fix would be to do 
something like this:
timeout.QuadPart = (ULONGLONG)((ULONG)_Xtime_diff_to_millis(xt)) * -10000;
Otherwise you can change the code to not use _Xtime_diff_to_millis.

Thanks,
