Clocks are used as inputs into decisions. So this doesn't matter as long as the decision process accounts for it. If I see that a meeting starts in 5 minutes, I'm not setting a timer get there in 300 seconds, I'm trying to decide if I have time to fill my water bottle on the way or not.

The post is a useful consideration to think if you are trying to do precise tasks though. See Keskival's post below about intervals vs moments to add some more precise ways of thinking.
