[TYPO3-ttnews] news-list-date shown as unix timestamp

[Thijs Hakkenberg]

Dear list,

On my tt_news based site news-list-date is shown as (I guess) unix 
timestamp:

http://dierenrecht.org/alle-persberichten/

I've tried  overriding with the script from the documentations example:

plugin.tt_news {
   archiveTitleCObject {
     10.strftime = %B - %Y
   }
   getRelatedCObject {
       20.strftime = %d.%m.%Y %H:%M
   }
   displaySingle {
     date_stdWrap.strftime= %d.%m.%y
     time_stdWrap.strftime= %H:%M
   }
   displayLatest {
     date_stdWrap.strftime= %d.%m.%y
     time_stdWrap.strftime= %H:%M
   }
   displayList {
     date_stdWrap.strftime= %A %d. %B %Y
     time_stdWrap.strftime= %d.%m.%y %H:%M
   }
}

but it doesnt fix anything.

Ideas?
