The posting timestamp is temporarily adjusted, such that people don't complain about a week day old submission being on the front page.

The comment timestamps are temporarily adjusted to be consistent with the adjusted posting times, such that readers aren't confused by the comments predating the apparent posting time.

The timestamps will revert back to their original values in a few days.

What I don't understand is why this went into the second chance pool if the original submission made it to the front page and got >100 points.
