Upon investigating, Morwraith, it appears you were saved to Icecrown Citadel on 9/10/2010 at 1:21AM GMT (Please note that GMT is 7 hours ahead of Pacific Standard Time, so this would mean sometime in the early evening on the 9th).
In the time you were in there, you received several Emblems of Frost and completed the weekly ICC quest, which was Securing the Ramparts.
If you don't remember this raid, do you think anyone you know with access to your account and authenticator may have logged in to heal, perhaps? If so, I highly advise you hide your Authenticator in a location only known to you, and perhaps change your account password.
