Question

I am trying to get the same Created, Accessed and Modified dates as appears in the windows properties as in:

But am finding the times are consistently 30 minutes out:

Believe it may have something to do with timezones/daylight savings but have been unable to find a solution. Have tried looking at:
TimeZone Bias and adjusting and looking at different methods including:
How to get create/last modified dates of a file in Delphi?

Current code:

var
MyFd TWin32FindData;
FName: string;
MyTime: TFileTime;
MySysTime: TSystemTime;
myDate, CreateTime, AccessTime, ModTime: TDateTime; 
Begin
 ...
 FindFirstFile(PChar(FName), MyFd);
 MyTime:=MyFd.ftCreationTime;
 FileTimeToSystemTime(MyTime, MySysTime);
 myDate := EncodeDateTime(MySysTime.wYear, MySysTime.wMonth, MySysTime.wDay, MySysTime.wHour,
 MySysTime.wMinute, MySysTime.wSecond, MySysTime.wMilliseconds);
 Memo1.Lines.Add('Created: '+ FormatDateTime('dddd, d mmmm yyyy, hh:mm:ss ampm', MyDate));
 ...

Any help appreciated

Thanks

I’m not sure what’s wrong with your current code, but I believe this code will do what you need, using standard Windows API calls.

procedure TMyForm.ReportFileTimes(const FileName: string);

  procedure ReportTime(const Name: string; const FileTime: TFileTime);
  var
    SystemTime, LocalTime: TSystemTime;
  begin
    if not FileTimeToSystemTime(FileTime, SystemTime) then
      RaiseLastOSError;
    if not SystemTimeToTzSpecificLocalTime(nil, SystemTime, LocalTime) then
      RaiseLastOSError;
    Memo1.Lines.Add(Name + ': ' + DateTimeToStr(SystemTimeToDateTime(LocalTime)));
  end;

var
  fad: TWin32FileAttributeData;

begin
  if not GetFileAttributesEx(PChar(FileName), GetFileExInfoStandard, @fad) then
    RaiseLastOSError;
  Memo1.Clear;
  Memo1.Lines.Add(FileName);
  ReportTime('Created', fad.ftCreationTime);
  ReportTime('Modified', fad.ftLastWriteTime);
  ReportTime('Accessed', fad.ftLastAccessTime);
end;

procedure TMyForm.Button1Click(Sender: TObject);
begin
  ReportFileTimes(Edit1.Text);
end;
