I turned mine in a couple days ago, but I also thought that the deadline was for 9:59 PM GMT, since every contest before now's had a deadline some time in the evening.
chair, for next contest, would it be possible for you to indicate AM/PM so chefs don't think they have an extra 12 hours and are accidentally tardy? most of us don't use military time, so aren't in the habit of assuming that you necessarily mean AM.
