To answer this question, it depends on which level you are.
When some so-call masters tell you that the building time is important, that is only reflect that they never do any Feng Shui researches. What they have learnt is only the fake Feng Shui.
If you have done a lot of Feng Shui researches, you will totally agree with me in my point of view. Because the experiences will tell you that a lot of ancient houses or graves did not have any records of building time. In these cases, how could you do the research? Those researches become meaningless.
Therefore before you claim yourself as a professional Feng Shui expect, make sure that you can tell the history of the house without asking any information which proof to be true by your client. That is what we call, “Real Professional”. Otherwise, you are only a joker.
