It's a nice analysis but he misses the fact that the Eastern Europe timezone doesn't match office hours, in particular it'd mean he worked around evenings primarily (see this graph https://files.catbox.moe/4itspl.png)
I had noticed UTC+0300 commits in the repository under his name but I believed they might have been simply committed by the main Finnish maintainer who is in the UTC+0300 timezone.

I doubt the git commit timestamps are faked, since actually faking them is somewhat difficult to do consistently (you would time travel frequently). I don't think there is some kind of github API for this, however from what I've seen they seem to match up with the same work timespan you see in the commit timestamps.
