Countdown Timer Issue

For users outside of Chicago, the countdown timer doesn’t seem to be taking their time zone into consideration…. How do we keep it connected to Chicago Time for everyone?
There is no way to show you, other than try for yourself. It should be counting down to 10am CT and depending on where you are in the world, it’s not counting down correctly. We need it to be 10am CT for everyone.
