I just posted a new News post, and it's stamped with yesterday's date. I also noticed this when I scheduled an event on the calendar. The site seems to think it's one day behind. I double-checked the Time Zone, and everything checks out.
Unusual indeed. This would be a bug that had nothing to do with the patch interestingly. This is going to be fixed with the next scheduled update, which is focusing on the news page and forum system.
