Is it just me, or is HN messing up dates?

We had this thread, for example, that I could have swore was a week ago, and yet it says it was 1 day ago.

If you can go back to your previous comments, and look at the dates for when it said they were posted, I would be curious to see if you are also seeing strangely low dates. Or maybe my mind is just playing tricks on me.
