It's not a glitch or an error, it's how the second chance pool works. They give them a new time when they get a fresh start. Their timestamp is temporarily updated, and any existing comments get that same timestamp. I think (but have never seen this confirmed) that this is a way to game the existing voting system (posts are ranked by a combination of votes, age, and comment activity). By giving them an artificially "young" age they move up in the ranking to hit the front page, giving them a chance for more votes (to remain on the front page) and comments. After a few hours the original timestamp gets restored. Revisit this tomorrow (certainly) or in a few hours and the times will change.
