This is why I hate WordPress. They create a notification at the top of the dashboard area, constantly reminding me that my WordPress version is obsolete and I need to update it. They promise me that 2.9.1 will fix many of the previous problems brought about by 2.9 …and I believed them.
Fast forward 5 minutes later, and I'm screaming and pulling my hair out because my website is showing a time 5 hours ahead of New York again! Fuck you WordPress development team.
Update: the advice that I used from NSLog();'s post about WordPress still works.

On the bright side (ha), there's been good movement on the bug:
