technology tree Does the technology tree match the year it was actually invented?

what i want to explain here is that when we research Nukes, the year will be 1945? (think of the scenario 1440)

i suggest the research is slower if you research something ahead of time

i didnt think it would be a very good idea because the technology tree is very large (50-10 years difference between researches)
There can't be a system similar to hoi4
