[ROOT] Time labels bug?

Hello,

I think the macro below shows a bug in either Datetime::Convert or in
drawing time labels. It always gives two hours shift, i.e. I see 6
instead of 8 and 14 instead of 16 hours.

Regards,
Anton

{
  TDatime Datime1;
  TDatime Datime2;

  Datime1.Set(98, 10, 24, 8, 20, 0);
  Datime2.Set(98, 10, 24, 16, 20, 0);

  TGraph Graph;

  Graph.SetPoint(0, Datime1.Convert(), 10);
  Graph.SetPoint(1, Datime2.Convert(), 20);

    TH2F *Hist = new TH2F("Hist", "Hist", 100, Datime1.Convert(),
Datime2.Convert(), 100, 0, 50);

    Hist->GetXaxis()->SetLabelFont(43);
    Hist->GetYaxis()->SetLabelFont(43);
    Hist->GetXaxis()->SetLabelSize(14);
    Hist->GetYaxis()->SetLabelSize(14);
    Hist->GetXaxis()->SetTimeDisplay(1);
    Hist->GetXaxis()->SetTimeFormat("%H:%M");
    Hist->GetXaxis()->UnZoom();
    Hist->GetYaxis()->UnZoom();
    Hist->SetStats(kFALSE);

    Hist->Draw();

  Graph.Draw();
}
