C++ GetProcessTimes()不会随时间改变值

#include <iostream>
#include <Windows.h>
int main()
    int processID = 14532;
    HANDLE processHandle = OpenProcess(PROCESS_QUERY_INFORMATION, FALSE, processID);
    if (processHandle == NULL) {
        return -1;
    FILETIME ftProcCreation, ftProcExit, ftProcKernel, ftProcUser;
    for (int i = 0; i < 10; i++) {
        if (!GetProcessTimes(GetCurrentProcess(), &ftProcCreation,
            &ftProcExit, &ftProcKernel, &ftProcUser)) {
            return -1;
        LARGE_INTEGER lKernel, lUser;
        lKernel.LowPart = ftProcKernel.dwLowDateTime;
        lKernel.HighPart = ftProcKernel.dwHighDateTime;
        lUser.LowPart = ftProcUser.dwLowDateTime;
        lUser.HighPart = ftProcUser.dwHighDateTime;
        printf("%lld : %lld\n", lKernel.QuadPart, lUser.QuadPart);
        Sleep(250);
}
