Delphi clock in listview

I have a listview component on a form and would like one of the columns to be a clock counting down to zero.

Does anyone know how I can do this?

I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Would this be a different clock for every item in the listview?

put a timer on your form which has the ListView

in the OnTimer event change the value of the CountDown
and update the ListView

  TForm1 = class(TForm)
    fCountDown: integer;
procedure TForm1.Timer1OnTimer(Sender: TObject);
  if CountDown > -1 then
    CountDown := CountDown - 1;
    ListView1.Items.Item[0].SubItems[1] := IntToStr(CountDown);
  end else Timer1.Enabled := False;
