Once again, as having been said, it is best practice to let the break clock go until 31 minutes, 29 minutes and 59 seconds will not count. Remember that you are on a Electronic device where as it counts seconds also . It will count exactly down to the second from when you log off duty. Example is if yo log off at 1:05 pm and the actual time is 1:05 and 20 seconds your full break will not count unless you wait until 1:35 and 20 seconds. It is easier to wait until that extra minute goes by to make sure that the break is locked in. If not, plan on taking another 31 minute break and eventually you'll learn not to log back on duty at 30 minutes
