<p>I just read that the Common App uses Greenwich Time for some purposes and EST for others. You should be fine even if it says submitted on Jan 2nd. As of me, I couldn’t submit at all because of issues with the Common App website. Got error messages every time I tried to submit and now I cannot log in at all. I have contacted both Columbia and the Common App to see if there’s anything I can do. You should probably do that, too. Send a quick e-mail to the Common App and Columbia Admissions to make sure that you’re okay.</p>
