Delaying and Controlling Servo with Arduino board

I am brand new to the world of Arduino and have recently purchased the Uno and a servo to help me build a project. I need 1 servo to wait 16 hours then rotate 120 degrees. It seems simple (and probably is) but I am having alot of trouble finding the right methods to do so.

If anyone could help/ give advice on what to do that would be much appreciated!

Thanks!

First off read this

Play with it and get to see how servos move and how to control them.

Then think what you want to do, your description sounds a bit stupid. Maybe you want to use a real time clock module? Maybe you want to do something after it has moved?

Maybe you could get a staff member to help you.
