Data changes automatically after timer

I am not sure if this is possible but it would a be a great feature/plugin

Basically I would to make to make minor changes to home page and after a set time it would revert back to the previous version this would be a great feature if automated.

Ie from set period of the day the ie from 10AM TO 9PM the page would be the same. After this time the data should revert back to the previous version.

Does anyone know if there is a plugin that can do this.
