SharePoint 2010 date key filters are 1 day off

Strange thing on the SharePoint sites here.
I am working with a long list of items and I am using key filters (metadata navigation functionality).

When I search for all items with creation date on (for example, DDMMYYYY) 05/05/2010, it will show me all items with creation date 04/05/2010.
So my key filters are 1 day off ! This is of course quite strange and not really useful to my clients. After a long and extensive search we found that Microsoft put a solution in their last cumulative update.

Description of the SharePoint Server 2010 cumulative update package (MOSS server-package): April 28, 2011
Issues that this hotfix package fixes
Consider the following scenario:
o You set the time zone as Coordinated Universal Time (UTC) time in SharePoint Server 2010.
o You add a key filter that is based on the Date Time field in a document library.
o You set the key filter to the date when a document was uploaded.
o You search for the document.

In this scenario, the key filter does not function correctly. Therefore, the document does not display in the search results.
