That is a completely different situation altogether. Generally that situation arises when much of a match has been rained out, so the captains agree to set a declaration target to bring about the possibility of a result. The bowlers (usually players who would never normally bowl) then give away runs until the declaration target is met. There are a few examples of centuries being scored in 20-odd minutes because of this, but Wisden does not recognise these as records.
Often double declarations (with the score on 0/0) are used as well; there is one instance of this occurring in Tests - England v South Africa four or five years ago, which England ended up winning, batting in the fourth innings. It attracted some controversy at the time, but is probably even more suspect now, given that the RSA captain in that game was one Hansie Cronje.
Edit: Here's the link
to that Test match. Very suspect indeed, given that RSA declared twice (actually declared once and forfeited the second innings) and it allowed England to win the series 2-1. Not many captains would be willing to take that risk, especially in a home series.
