i want to set my ads show out at 8pm - 8am in malaysia time, but i dont know how. can anyone tell me?
What platform is your site running on? If it's static HTML you might have a little more work, but if it's running on a PHP-based CMS, there is probably a plugin or another easy way to get it working.
In your campaign settings - go to >Advanced Settings > Ad scheduling. (what on earth is the post above me taking about?)
Find out what time zone your account is setup in. Then you will know what time to set your account to.
