How do I display an object for a set time?

I need to display in succession, a 3-2-1 countdown timer. I do not know how to display text for a specified time. Can you help me?

Thanks

UPDATE

I figured it out. Here's the code I used for a 3-2-1 countdown:

1 2	countdown3 = display.newText("3", 512, 384, "HelveticaNeue", 72) timer.performWithDelay(1500, countdown2, 1)

Thanks for sharing; glad you got it sorted :)

that's one way to do it.
here's another one:

local countDownNumber = 3
local countdownTxt = display.newText( countDownNumber, 100, 100,  native.systemFont , 72)
local theTimer 
function countdown ()
                countdownTxt.text = countDownNumber
                countDownNumber = countDownNumber - 1
                if countDownNumber == -1 then
                        countdownTxt.text = "GO!"
                        timer.cancel (theTimer)
                        -- call your startGame function
                        return
                end     
                theTimer = timer.performWithDelay(1500, countdown, 1)
end
countdown ()
