It would be great if [[Special:Interwiki]] could have a date that the interwikis were last updated. Current interwikis could be old and no evidence available to know from when they occurred.
Bit difficult to do if a wiki is using the Interwiki extension, and the interwiki table, as we've not really anywhere to store this data. If we're using a cache file, I guess we can just stat it, and maybe store in memcached for 24 hours or so (purely it won't be updated that often)
