Exactly - once you have got beyond a couple of days whether a document is written 20 years, 40 years or 100 years after an event is irrelevant in terms of validity and accuracy.
Much more important is who wrote the document, what sources they used and, critically, why they wrote it. And that last point is so important. If the author is partial rather than impartial it is unlikely that the result will show anything other than bias.
So to go back to my WWI example. I think you are much more likely to gain an impartial and balanced assessment of WWI from documents written now than you would have done from documents written in either the UK or Germany in the late 1930s and early 1940s, when the fact that we were about to (or already at war with) Germany would have massively biased the ability of writers to be completely impartial when looking back at WWI.
