Patch Management - Windows & RHEL/CentOS based on Date

Hi All, Does anyone know of a patch management system that will allow us to control the roll out of patches, specifically for Windows but Linux would be nice too, that can use a date to limit whether a patch is rolled out. Ie. Patch to date set to 2012-06-10 So all patches released up to 2012-06-10 will be offer to requesting client. Any patches released after 2012-06-10 will be hidden/not offered until the "Patch to Date" is moved forward.
