Please clarify what your expectations are.

Keep all the time keeping stuff on the server side is my advice to you. When an exam is started by a user a record is persistently stored on the server side (DBMS, Sessions, etc.). The webpages that make up the different questions of your exam will then query the server\website via Ajax (client side). The value returned could consist of the number of seconds (minutes, etc.) left for the exam so you can show the student/user how much time is left. As soon as that count has gone to zero the page will redirect to a page that tells the student/user the exam is over.
Another benefit of having the timing stuff on the server side is that it'll be close to impossible to cheat. If a student would somehow manage to still submit answers to questions the server side would reject them as it is known that the period of the exam has elapsed.

Best Regards,
