Gedmatch? In what year did it all happen?

[Sacred Root]

Hi all.
What period does Gedmatch refer to?
For example, I could be considered 100% the modern 2022 native of a country. However, I would be only 70% native to 1200 AD, with the remaining 30% coming from other areas. So what kind of years does Gedmatch refer to when it offers all these percentages and results?
