I just edited [[St. Louis Park, Minnesota]]. The edit history shows this: # (cur) (last) 20:47, 21 July 2005 Michael Hardy (→Education) # (cur) (last) 20:46, 21 July 2005 Michael Hardy (attempting to fix a mangled link) The ostensibly last edit is summarized by the word "Education", that being the section heading. Clicking on "last" informs me that the edit consisted of changing the [[U.S. Department of Education]] to [[the U.S. Department of Education]]. In reality, my summary for the last edit, NOT the one BEFORE that, said "attempting to fix mangled link", and in fact in that edit I changed [[the U.S. Department of Education]] to the [[U.S. Department of Education]].
Another aspect, in the diff-view (http://en.wikipedia.org/w/index.php?title=St._Louis_Park%2C_Minnesota&diff=19325761&oldid=19282350): Clicking on next edit doesnt show the Edit summarized with Education

(In reply to comment #4) > *note* > A multiple sort key is required here: > first "timespamp", then "pageid" / "page_id" (?) The multiple sort criteria first "timestamp", then "pageid" / "page_id" (?) at history/diff should be the same as at "Special:Contributions/foo" and [[Special:Recentchanges]]. The links at Special:Contributions/foo are using diff=prev&oldid=<oldid_no>. The links at Special:Recentchanges are using curid=<curid_no>&diff=<diff_no>&oldid=<oldid_no>. Both seems to be sorted by timestamp and <diff_no>. best regards reinhardt [[user:gangleri]] *note* history/diff is not mentioned at Bug 2468: The code that generates the namespace form for Special:Contributions, Special:Allpages and Special:Recentchanges should be merged but I think that sort criterias should be the same exept for Special:Allpages

I have another example of the "Next diff", "Prev diff" links not working right. See http://commons.wikimedia.org/w/index.php?title=Template:Description&diff=next&oldid=246447 That link is supposed to show the difference between revision 246447 and the chronologically next revision. Instead, it shows the difference between 246447 and the ''previous'' revision, 246448. Apparently the diff view assumes that page ID numbers are in chronological order, when they really aren't.
Same problem appears here also: http://de.wikipedia.org/w/index.php?title=MediaWiki:Notargettext&diff=next&oldid=1399036 As you can see in the history, it's in the wrong order: http://de.wikipedia.org/w/index.php?title=MediaWiki:Notargettext&action=history

Probably the same problem appears here: http://ksh.wikipedia.org/w/index.php?title=User_talk:Purodha&direction=next&oldid=6719 the "Newer revision→" links to: http://ksh.wikipedia.org/w/index.php?title=User_talk:Purodha&direction=next&oldid=6720 , following the link does not display the next newer revision, but the most current as of today. Reason being most likely the oldid's not being in date/time order. Here, the revisions newer than oldid=6720 have been created before all the older versions up to and including oldid=6720 were created via Special:Import. As of now, no newer revisions have been made since.

Changing summary, confusing to say "the edit history is wrong" when sorting based on timestamp is the expected behaviour from a user's perspective, making the edit history 'correct' and diff links 'wrong'.
*** Bug 21741 has been marked as a duplicate of this bug. ***
Per Gurch, the issue is not that the edit history is wrong, but that the timestamps are wrong. This isn't MediaWiki's fault, if anything it's either a WikiMedia server cluster bug or it's that we should be using something other than timestamps to sort edits. There be dragons, in my opinion, with using something other than timestamp to sort because then users get confused, and short of buying a few atomic clocks there's no way to improve timestamp accuracy, as I presume each cluster is NTPing together. Is there anything to be done on this bug or can it be closed?
I don't think it's relevant whether the timestamps are right or wrong. There will be valid reasons where sorting by ID and by timestamp give different results (e.g. transwiki imports, or article merges). The problem is that the sorting is done by timestamps in one place (revision list), and IDs in another ('diff with previous' link). All sorting of revisions should be done by timestamp, then ID, in all cases. This would remove inconsistencies within the various user interfaces where revisions are displayed/used. Problems on the cluster that result in incorrect timestamps (if they exist) are a completely separate issue, and should be handled by a different bug.
The effects of this bug have changed a bit since the MediaWiki 1.18 update. The "diff prev"/"diff next" links are still sorted by revision ID, but the number of intermediate revisions found above the diff is now calculated by date rather than revision ID.
