Ok, I really can't understand how forefront updates work and I can't understand where the problem is.
I have a Forefront Client Security on a windows server 2003 sp2. Updates are automatically downloaded and installed with WSUS 3.0 SP2. At the moment if I open forefront client on a computer I read:

Well, according on the link (http://www.microsoft.com/security/portal/Definitions/HowToForefront.aspx) it is the last update at the moment I'm writing.
So why 12/10/2011? WSUS downloaded it today (13/10/2011) at 9,08 and both the WSUS and the Forefront servers have the correct time.
Why this date for updates instead of 13.10.11?
Thanks in advance
