On the image in the URL, the exif metadata shown tells me the picture was taken this very moment (the description says it was taken in 2003). When I refresh (some time later), the time does not change on meta, but does so for the same page on en.wikipedia.org (where I am logged on), so I assume it's cached on meta because I'm not logged on there. If the picture file does not contain useful information in these fields, they should be left blank instead of showing false data. I suppose the picture file contains 0 as the date, which is then converted by wfTimestamp into time().
Fixed in r18861 The date was 0000:00:00 00:00:00, it now reports 'Unknown date' by using the message 'exif-unknowndate'
