Updates were installed: Date different

I have a odd issue, I think.    My updates are getting applied.  but, it shows in the history correctly.  but, the "Updates were installed"  is different.   I have other users that show the same thing.   The "Updates were installed"  can be like a month or so later. 

In this example: it says my updates were installed  6/27/2013,  but my history shown below, shows the correct date  7/15/2013 which is correct.
