You mean the timer on the jam page? https://itch.io/jam/a-game-by-its-cover-2016
It's already been updated. The original due date was August 1 @ 2:00 AM (CEST), now it's August 8 @ 2:00 AM (CEST).
Don't worry about submitting your game. If you miss the deadline, just let us know. We can add your game to the jam manually, even after the deadline. :)
You could also submit a placeholder now and just update it whenever. I personally don't like crunch, but unfortunately the game jam format in general implicitly expects people to crunch (because of the very limited time frame). I wanted to avoid this a bit, so I made the jam a month long, and even extended the deadline.
Really, don't worry. Just make something and submit whatever. This is supposed to be relaxing and fun.
