Webmasters who are promoting affiliate programs with AdWords, will now be able to set up schedules for their campaigns, both on a hourly and daily basis. To activate this new feature, click “edit campaign settings” and then turn on “Ad scheduling”.
You will be able to set up to two time periods/day for which you can even adjust the pricing of you ads in % (in advanced mode). Another useful feature is that edits can be made on a daily basis or as bulk for the entire week.
