[development] views date filter of one day

Hi all, I have a view that filters on a cck date field and is set as <= now. The problem is that the view also returns nodes with dates that are one day later then now. I've seen some posts that mention the timezone settings could cause this, but couldn't find any solutions. The timezone is set to Europe/Brussels but the cck date field doesn't have hour granularity (in which case timezone conversion is not possible on cck field lvl). Weird thing is that when I use the views preview button in the views ui and copy the query (or copy the query from the dev ouput) into phpmyadmin and run it there, I do get the correct results. Any ideas ? HnLn
