VS2010新建控制台空项目，加入C++代码：

#include <Windows.h>#include <stdio.h>bool ConvertFileTimeToLocalTime(const FILETIME *lpFileTime, SYSTEMTIME *lpSystemTime){if (!lpFileTime || !lpSystemTime) {return false;}FILETIME ftLocal;FileTimeToLocalFileTime(lpFileTime, &ftLocal);FileTimeToSystemTime(&ftLocal, lpSystemTime);return true;}bool ConvertLocalTimeToFileTime(const SYSTEMTIME *lpSystemTime, FILETIME *lpFileTime){if (!lpSystemTime || !lpFileTime) {return false;}FILETIME ftLocal;SystemTimeToFileTime(lpSystemTime, &ftLocal);LocalFileTimeToFileTime(&ftLocal, lpFileTime);return true;}int main(){HANDLE hFile;FILETIME ftCreate, ftAccess, ftWrite;SYSTEMTIME stCreate, stAccess, stWrite;int year, month, day;hFile = CreateFile(L"C:\\1.txt", GENERIC_READ | GENERIC_WRITE, 0, NULL, OPEN_EXISTING, FILE_FLAG_BACKUP_SEMANTICS, NULL);if (INVALID_HANDLE_VALUE == hFile) {printf("CreateFile error: %d", GetLastError());ExitProcess(0);}GetFileTime(hFile, &ftCreate, &ftAccess, &ftWrite);ConvertFileTimeToLocalTime(&ftCreate, &stCreate);ConvertFileTimeToLocalTime(&ftAccess, &stAccess);ConvertFileTimeToLocalTime(&ftWrite, &stWrite);printf("yyyy-MM-dd:");scanf("%d-%d-%d", &year, &month, &day);stAccess.wYear = stWrite.wYear = year;stAccess.wMonth = stWrite.wMonth = month;stAccess.wDay = stWrite.wDay = day;ConvertLocalTimeToFileTime(&stAccess, &ftAccess);ConvertLocalTimeToFileTime(&stWrite, &ftWrite);SetFileTime(hFile, &ftCreate, &ftAccess, &ftWrite);CloseHandle(hFile);return 0;}

只修改年月日，时分秒不变。
