One notices that RecentChanges now can put a "from=" parameter into the URL bar.
But one craves badly an additional "until=" or "to=" parameter.
E.g., for when one needs to know what happended during a certian hour back two years ago.
As to if it should be clickable, like from=, or just a note that one can add "until=" to the URI, that is up to you.
Yes perhaps there is an API, but we still think the from= is a big tease without a matching until= or to=.

Severity: enhancement
And then messages should be printed out "sorry, recent changes only has knowledge until 2008/5/5 ..." at the end of output that reaches the bottom of its memory.
Currently one just gets empty output, which doesn't distinguish "no changes" from "no knowledge".
That might be acceptible for the API, e.g., api.php?action=query&list=recentchanges&rcstart=2007122100000&rcend=2007122700000
but for Special:Recentchanges, it should be more verbose.
There also is the from/days conflict, which I will report in a different bug.
