landscape

Could you please try like this:
iTextSharp.text.pdf.PdfPage page =  iTextSharp.text.pdf.PdfPage.LANDSCAPE;
instead of:
       iTextSharp.text.Rectangle page = doc.PageSize;

Error      1      Cannot implicitly convert type 'iTextSharp.text.pdf.PdfNumber' to 'iTextSharp.text.pdf.PdfPage'      

also I am setting to height and weight... it is complain that too when I take out that line..
Error      2      'iTextSharp.text.pdf.PdfPage' does not contain a definition for 'Width' and no extension method 'Width' accepting a first argument of type 'iTextSharp.text.pdf.PdfPage' could be found (are you missing a using directive or an assembly reference?)      

Does it helps you :

didnt help me no. :((

What did you get from the link??

didnt make the landscape oritentaion.. no error though..

you did it!! it worked..!! thank you so much!!. I am going to ask more question about this shortly.. if you want to take a look?

You know what I just discovered that because it is Document.NewPage();
  my title is not showing..!!

If you will visit the link you will see the use of:
Document.SetPageSize(PageSize.A4.Rotate());
before:  
Document.NewPage();
We need to rotate the page first and then declare that page. So,Once page is created rotation won't work as described in the link that will giv error.  
I was thinking from your title's point of view so the referenec i posted you didn't work. then I work on general page rotation and I found the helpful article.
 
 

depending on where I put that code it changes... the way I am sending you now will put it first page empty only shows date displays..than second page it shows my title and the table fine...
but I want to see those on the first page not second...

Document doc = new Document();
       
        PdfWriter writer = PdfWriter.GetInstance(doc, Response.OutputStream);
        Phrase phrase = new iTextSharp.text.Phrase(DateTime.UtcNow.ToString("yyyy-MM-dd HH:mm:ss") + " GMT", new iTextSharp.text.Font(iTextSharp.text.Font.COURIER, 5));

        doc.Open();     

        iTextSharp.text.Rectangle page = doc.PageSize;       
       
       

        PdfPTable head = new PdfPTable(1);
        head.TotalWidth = page.Width;

        PdfPCell c = new PdfPCell(phrase);
              
        c.Border = iTextSharp.text.Rectangle.NO_BORDER;
        c.VerticalAlignment = Element.ALIGN_TOP;
        c.HorizontalAlignment = Element.ALIGN_CENTER;
       
        head.AddCell(c);
        head.WriteSelectedRows(
            // first/last row; -1 writes all rows
          0, -1,
            // left offset
          0,
            // ** bottom** yPos of the table
          page.Height - doc.TopMargin + head.TotalHeight + 20,
          writer.DirectContent);
        doc.SetPageSize(PageSize.A4.Rotate());
        doc.NewPage(); 
        // add image to document
        iTextSharp.text.Image logo = iTextSharp.text.Image.GetInstance(Request.MapPath("~/GF2images/ogoPDF.jpg"));
        
        logo.Alignment = iTextSharp.text.Image.ALIGN_LEFT;
        logo.ScalePercent(60f);
        doc.Add(logo);

        // report "title"
        Paragraph p = new Paragraph("Test Title", new iTextSharp.text.Font(iTextSharp.text.Font.HELVETICA, 10f, iTextSharp.text.Font.BOLD));
        p.Alignment = 1;
        doc.Add(p);

        
        // add tabular data
       
        doc.Add(my_table());
        doc.Close();
