I don't know if this is the right place to post my question. But something has been driving me crazy for the last weeks. Let's say I close my macbook at 11AM. And then I go home from my class. And I get home at 11:30AM, and then I open my macbook again. It doesn't update the time to 11:30AM. I missed two classes already because of that. I'm using ML 10.8.2 in a MacBook Pro Late 2011. I tried both checking and unchecking the "automatically adjust time". I have no idea what to do. Thanks!
