Hi there, Catwen.
It's not unusual for the armory to be behind by a few days (though not always), but in this particular case it seems to be out by an unusually long time. We're currently looking into it and hope to have more information soon.
In the meantime, a few players have found that they can get the armory to update by visiting Dalaran and logging out there. Give that a try and see if it helps. :)
