Please, please, please make a louder timezone for bookings!

My students come from all over the world. When the register for the university they often set their account timezone as their home timezone. Then they are very confused later when living at the University when their bookings are all off. There is a pretty little timezone icon, but I want a warning or something if their timezone and my timezone are a mismatch. Something, anything to help them to successfully sign up and not be surprised when I tell them they do not have an appointment for the time they "clicked".

The timezone needs to be very loud on the page. Currently it is behind that beautiful globe button that no student is going to see.
