Why does it say your comment was made 2 days ago, when the thread has only been up for 6 hours?
It's a HN thing, not down to the commenter. Sometimes threads are reactivated if the mods think a low profile discussion is worth a second chance or boost. The submission time doesn't always reflect the original submission. Sometimes it's due to a comment move or thread merge.
PR companies have found that getting ahead of controversies is useful, so they invented time travel.

(aftbit already mentioned this link downthread but perhaps it's helpful to say this explicitly.)
Edit: actually I should probably pin that to the top. Done now. Sorry for the confusion!
