The Qualify Time (aka Par Time in MBP) is the time that you need to get to qualify in a level. Some levels have qualify times, and if you do not finish before the time runs out, you will have to retry the level. The Time Travelbonus will give you Bonus Time, which is time you save by activating the PowerUp. In Marble Blast Gold, there is no way to tell if the qualify time has passed, meaning that you have to know the time before entering the level. However, in Marble Blast Platinum, the game will alert you when the timer starts to get close to over.
