I wrote a little thing for the HTML Hell advent calendar from @matuzo.at — but on a good improvement to HTML rather than a hellish thing 🙂

More detailed paint timings coming to LCP.
TLDR:
- paintTime is after the style&layout and should be roughly interoperable between browsers.
- presentationTime is implementation specific (Chrome's is pretty near when pixels are actually drawn).
LCP time stays the same as the latest timestamp.
