It matters because some people want to know the "official" time. Just for giggles, let's say you want to volt and were running to stand in line because you knew you had 50 seconds to get there, but the person closing off the line had a different time...bam. Yes I know that makes no sense and is total bs, but I think you might get the point.
I know I set my watch by the atomic clock and it loses about a minute a week. Just something I do. Does it matter? No, for most it does not. I blame it on having a engineering degree.🙄

Since this is just for giggles, in that situation I'd say you didn't plan well for contingencies. My point is that we can't assume anyone else in the world has their clocks sync'd exactly correct, so you have to allow for that. Whether your timepiece is a minute slow or fast shouldn't really matter. Just my opinion, I realize different people obsess over different things so different stuff is important to them. In the long run though it really just doesn't matter.
