Problem with Time Display in TGraph

I am running ROOT version 5.11 on a PC with Windows XP. I have run the following macro.

   TDatime td(2006,5,2,0,0,0);
   TGraph *gr = new TGraph();

   gr->SetPoint(0,0,0);
   gr->SetPoint(1,60,1);
   gr->GetHistogram()->GetXaxis()->SetTimeOffset(td->Convert(0));
   gr->GetHistogram()->GetXaxis()->SetTimeDisplay(1);
   gr->GetXaxis()->SetLabelSize(0.02);
   gr->GetXaxis()->SetTimeFormat("%Y\/%m\/%d %H\:%M\:%S");
   gr->Draw("ALP");

I expected the first point to be 5/2/2006 0:00:00, but when the canvas was displayed it showed the first point to be 5/2/2006 01:00:00. Am I doing something wrong?

Thanks,
