As I suggested before, the issue of "when the build was made" is not
entirely straightforward in this case. Most components of the build
were made on November 20. The kernel and FE were built on that day, and
SystemInformation[] reflects that. But the installer was built later
(on Dec. 1, I think).

In that context, I don't even properly understand what question you're
asking. But I'm telling you what the build numbers were and what they
represent. It's not secret information.

That's why there's so little difference between the Windows and Mac creation dates, despite the fact that you installed the updated Windows version.
