The default Global Address List (GAL) does not update the WhenChanged attribute
when I use the cmdlet Get-GlobalAddressList | fl it shows that the default GAL was last changed in July 2012! while in the OWA I can see new users and update, and the OABs do update, but for the users the OAB is not updated unless I delete the stored on from the local HDD So I would like to know if why WhenChanged attribute is not updating!

That changed Date represents the date the GAL "object" was changed, not when it was updated with additions or removals of mail-enabled accounts. So , if you changed the Recipient Filter or something similar, then that date would be updated. Twitter!:
