Hi, we have a strange behavior in arwiki. The history page of [[ar:mediawiki:Nstab-mediawiki]] gives 
six entries with no deleted edits:

http://ar.wikipedia.org/w/index.php?title=mediawiki:Nstab-mediawiki&action=history

but its arrange is a bit strange, the dates are not consistent with the Page IDs

Note the second and thierd oldids. The history command arrange them based on the date (not as I did 
above), giving oldid=8604 afer oldid=43955, as it has a newer date.

But the actual content is arranged based on the oldid. The page was last rendering the contents of 
oldid=43955. Then I modifed the content to oldid=501376 then reverted it using the revert command , ( 
as an admin ) and got oldid=501377, which was identical to oldid=8604 not oldid=43955.

I can only assume that there was something wrong with the clock of the servers. ( at least I hope so ).
