Использование ETW для печати метки времени при переключении контекста

Я использую следующий код, который я нашел на веб-сайте Microsoft. Он успешно компилируется и выводит файл журнала, как и предполагалось:

#include "stdafx.h"
#define INITGUID  // Include this #define to use SystemTraceControlGuid in Evntrace.h.

#include <windows.h>
#include <stdio.h>
#include <conio.h>
#include <strsafe.h>
#include <wmistr.h>
#include <evntrace.h>

#define LOGFILE_PATH L"C:\\Documents and Settings\\Administrator\\My Documents\\My Dropbox\\Log.etl"
void wmain(void)
{

ULONG status = ERROR_SUCCESS;
TRACEHANDLE SessionHandle = 0;
EVENT_TRACE_PROPERTIES* pSessionProperties = NULL;
ULONG BufferSize = 0;

// Allocate memory for the session properties. The memory must
// be large enough to include the log file name and session name,
// which get appended to the end of the session properties structure.

BufferSize = sizeof(EVENT_TRACE_PROPERTIES) + sizeof(LOGFILE_PATH) + sizeof(KERNEL_LOGGER_NAME);
pSessionProperties = (EVENT_TRACE_PROPERTIES*) malloc(BufferSize);
if (NULL == pSessionProperties)
{
wprintf(L"Unable to allocate %d bytes for properties structure.\n", BufferSize);

goto cleanup;
}

// Set the session properties. You only append the log file name
// to the properties structure; the StartTrace function appends
// the session name for you.

ZeroMemory(pSessionProperties, BufferSize);
pSessionProperties->Wnode.BufferSize = BufferSize;
pSessionProperties->Wnode.Flags = WNODE_FLAG_TRACED_GUID;
pSessionProperties->Wnode.ClientContext = 1; //QPC clock resolution
pSessionProperties->Wnode.Guid = SystemTraceControlGuid;
pSessionProperties->EnableFlags = EVENT_TRACE_FLAG_CSWITCH;
pSessionProperties->LogFileMode = EVENT_TRACE_FILE_MODE_CIRCULAR;
pSessionProperties->MaximumFileSize = 5;  // 5 MB
pSessionProperties->LoggerNameOffset = sizeof(EVENT_TRACE_PROPERTIES);
pSessionProperties->LogFileNameOffset = sizeof(EVENT_TRACE_PROPERTIES) + sizeof(KERNEL_LOGGER_NAME);
StringCbCopy((LPWSTR)((char*)pSessionProperties + pSessionProperties->LogFileNameOffset), sizeof(LOGFILE_PATH), LOGFILE_PATH);

// Create the trace session.

status = StartTrace((PTRACEHANDLE)&SessionHandle, KERNEL_LOGGER_NAME, pSessionProperties);

if (ERROR_SUCCESS != status)
{
if (ERROR_ALREADY_EXISTS == status)
{
wprintf(L"The NT Kernel Logger session is already in use.\n");
}
else
{
wprintf(L"EnableTrace() failed with %lu\n", status);
getchar();
}

goto cleanup;
}

wprintf(L"Press any key to end trace session ");
_getch();

cleanup:

if (SessionHandle)
{
status = ControlTrace(SessionHandle, KERNEL_LOGGER_NAME, pSessionProperties, EVENT_TRACE_CONTROL_STOP);

if (ERROR_SUCCESS != status)
{
wprintf(L"ControlTrace(stop) failed with %lu\n", status);
}
}

if (pSessionProperties)
free(pSessionProperties);
}

Мне интересно, есть ли способ изменить этот код, чтобы он печатал отметку времени при обнаружении переключения контекста. У кого-нибудь есть идеи?
