The default calendar app has a custom timestamp in the top right corner showing the time until the event, rather than the time since the notification was generated. For event type notifications, this is clearly superior, as a very quick glance will tell you how many minutes until your next event. Granted, you don't have to be a beautiful mind to do that arithmetic in your head, but it's still a useful feature.
As I haven't found any third-party app supporting this, I assume this is Apple using proprietary and private APIs not available to other developers?
