When we do this, the submission timestamp on the front page becomes the time it was put in the queue, approximately. That's why it looked like a later post than yours. I don't like doing this, but not doing it invariably triggers a barrage of questions and complaints ("what is this 2-day old story with 3 upvotes doing on the front page"). You can always see the original timestamp by looking at the submission in the user history (https://news.ycombinator.com/submitted?id=agnivade) or the site history (https://news.ycombinator.com/from?site=mozillagfx.wordpress....).
