Do you have this hardware ?
Can you provide more specifics on the timer ?
ie: What is it for ? ( a 10 minute count down timer maybe ?)

You would need to download the SerialGraphicLCD library to display text on the screen, after that is it really easy.

Just don't update the image faster than the display value changes. If it's a 1 second tick then update only on the second otherwise it may flicker.
