Timing help!

Hello everyone.

I have just noticed a new problem that I hope I can get some help fixing. I have done several presentations with 13 and it is getting easier to do. However I just noticed something. The time for the entire presentation is wrong. With '09 we would let our customers know how long the presentation was and the timer on the top would let the customer know how close they were to being finished. However with '13 it only counts quizmakers as 5 seconds. So a thirty minute presentation with 6 quizmakers in it could actually show up as only twenty minutes. Now the customer thinks that the presentation is actually only twenty minutes when in fact it is much longer.

Is there a work around to have the correct time show? 

PLEASE HELP!

thank you in advance for your assistance...
