Especially: "One interesting option that is missing is the ability to retrieve the latest version less than or equal to a given timestamp, thus giving the 'latest' state of the record at a certain point in time. Update: this is (obviously) possible: just use a range from 0 to the desired timestamp and set the max versions to 1 (thanks Jonathan)." Adding a time range to the Shell is trivial, currently it only implements a fixed TIMESTAMP though. You could also use a Scan call from the shell as that has a MINTIMESTAMP and MAXTIMESTAMP option. That is for 0.20.x, apparently "someone" forgot to port this to 0.89?
