Not really. "As of 1981, there is a country in Europe named Yugoslavia" is a fact that never stops being factual.

At least this is the view that many functional programmers like to use and I find it useful.

In that model, a statement that can vary in time isn't a fact.

That is a statement that requires you to reason within a temporal logic. And it is a statement that is not equivalent to "There is a country in Europe named Yugoslavia".
