According to our highly unscientific methods, time is not really precise. We're talking seconds, people! Who needs those extra milliseconds?
In fact, our team of highly trained and not-at-all-biased experts has calculated that the average human can only accurately perceive time within a 5-second margin of error. Anytime you're off by more than 5 seconds and you're basically a time-traveler.
Stay precise, friends!
