#include <time.h>
#include <utime.h>
#include <sys/stat.h>
const char *filename = "input.txt";
int main() {
struct stat foo;
time_t mtime;
struct utimbuf new_times;
stat(filename, &foo);
mtime = foo.st_mtime; /* seconds since the epoch */
new_times.actime = foo.st_atime; /* keep atime unchanged */
new_times.modtime = time(NULL); /* set mtime to current time */
utime(filename, &new_times);
return 0;

Windows (or the standard CRT, anyhow) has the same utimesfamily of functions that UNIX has.
Windows（或标准 CRT，无论如何）具有与UNIX相同的utimes系列函数。
struct _utimebuf t;
t.tma = 1265140799; // party like it's 1999
t.tmm = 1265140799;
_utime(fn, &t);
Using Win32 functions, FILE_BASIC_INFOcan be set using SetFileInformationByHandle.
使用Win32函数，FILE_BASIC_INFO可以使用设置SetFileInformationByHandle。
FILE_BASIC_INFO b;
b.CreationTime.QuadPart = 1265140799;
b.LastAccessTime.QuadPart = 1265140799;
b.LastWriteTime.QuadPart = 1265140799;
b.ChangeTime.QuadPart = 1265140799;
b.FileAttributes = GetFileAttributes(fn);
SetFileInformationByHandle(h, FileBasicInfo, &b, sizeof(b));

Use SetFileInformationByHandlewith FileInformationType as FILE_BASIC_INFO
使用SetFileInformationByHandle和 FileInformationType 作为 FILE_BASIC_INFO
