One thing that this article evokes is the 'I'm wrong and my belief is deeply held' aspect which technology people occasionally fall in to. Looking at the comments, with incorrect beliefs expressed as dicta ranging from just plain wrong, to incompletely specified, to ordinary confusion is giving my tech-PTSD a workout. There are topics in which the ordinary or common sense understanding of a thing actually interferes in understanding how that topic actually acts in reality when looked at closely or under complex conditions. The concept of time is one of those things. The best thing a naive developer can do when reasoning about time is to first know that almost everything they assume is wrong, and they don't even know what their assumptions are. The concept of 'location' is another of these topics. I would like to close this comment with a helpful link to a concise introduction for people to start with in clearing out the 'common sense' assumptions but I haven't ever found one, and haven't invested enough time to write one. Sorry. Links to same will be gratefully received.
