I'm told ChromeOS ships it nowadays, so I'm excited at the idea to
learn more about it, so that we can move forward a bit about the
fingerprinting issue.

I was not able to find any authoritative information about how they
run it. Their time sources [1] design doc is quite clearly outdated.
Where can I find up-to-date information on this topic? I assume one of
the dozens of Chromius Git repositories [2], but which one?
