Yes... in the FRED software, there are two countdown timers. One is for the amount of time remaining in the current block and the other is the amount of time left for the entire day. Once you enter your CIN (i.e. break the seal) on the test, the full day timer starts counting down from 8 hours and doesn't stop until you finish the test (or run out of time).
My test center today had a wall clock in our waiting room. When you click "Take a break" after a section, it gives you a countdown of your remaining break time. So make sure to do the math in your head, constantly so that you don't lose time on Block 7.
Also, note that you actually get only 45 minutes of allotted break time... It becomes up to 1 hour if you speed thru the tutorial. This surprised me, I did not find out until today.
