This seems like a Kobayashi Maru (a.k.a. a famous no-win situation test for budding starship captains in the Star Trek universe), but this isn't a simulator, this is real life. You'll never be in this situation. You'll always have more information about the sources for these dates/times. And that may give you enough context to make a decision, maybe not. But trying to solve the problem in the general sense is impossible.

> You'll never be in this situation

The article indicates the opposite: this is a real situation (it's explained why they are asking) and like Zach Holman states (somewhat exaggerated, true): unless your software has no users and is only one hour old, you'll find yourself in this situation.

No, the article doesn't reveal anything about where this data comes from, other than the vague "user input vs database" which is useless.

So their problem is real-world, and has a solution. We're supposed to solve the problem without the benefit of the context that they have, which makes it a contrived academic problem, which was my point.
