I think the time of a local event sounds much more important, and a photo of a calendar and a clock sounds much more frivolous. Also, you can't take photos of events that haven't happened yet, and it's precisely with events that haven't happened yet that you most need to store a timestamp and a timezone rather than a postgres "timestamp with timezone" (which does not involve a timezone at all). So the analogy doesn't really tell you how to use it well.
