I'm simply communicating the point of the article. Take it up with the author if you don't like it or don't agree. And he'll tell you that if sub-minute precision is necessary (i.e. someone would be reprimanded for being under 30 seconds late to a meeting) the simple solution is to include a second hand on those clocks, and there won't be any confusion. (Of course, what's the likelihood of a basic office wall clock being accurate to within 30 seconds anyway, but that's a whole other rabbit hole)
