That tells me the release date of the update but when should I assume my PA's will actually download and run the updates?  I am still on 266-1120 on my 4050 cluster and 268-1130 on my 500's.  Both are set up to check for updates every day at 1:00am and download and install and sync to peer...  Is it normal to see the 4050's behind in version from the 500's which are behnd according to teh dynamic update link of what is available?
