It's a platform-specific operation (no such standard/portable functions). See the snippet:

#include <windows.h>
bool ChFileTimeCrtd(const char* fname, const SYSTEMTIME* pst)
{
  HANDLE     h;
  FILETIME   ft;

  if (!pst || !SystemTimeToFileTime(pst,&ft))
     return false;
  h=CreateFile(fname,GENERIC_WRITE,FILE_SHARE_WRITE,
               0,OPEN_EXISTING,FILE_ATTRIBUTE_NORMAL,0);
  if (h == INVALID_HANDLE_VALUE)
     return false;

  BOOL rc = SetFileTime(h,&ft,0,0);
  CloseHandle(h);
  return rc != FALSE;
}

int main(int argc, char* argv[])
{
  SYSTEMTIME t;
  t.wYear  = 2001;
  t.wMonth = 1;
  t.wDay   = 1;
  t.wDayOfWeek = 0;
  t.wHour   = 17;
  t.wMinute = 0;
  t.wSecond = 0;
  t.wMilliseconds = 0;
  ChFileTimeCrtd("testfile.txt",&t);
  return 0;
}

See MSDN for full SetFileTime() parameters description.
Adjust ChFileTimeCrtd() interface as you wish.
Remember: it's UTC time. Correct with your timing zone.
