Scaling off Akatosh is inaccurate and time is not present throughout all of Oblivion. It is present in realms which the Daedric princes will time to be. We do not know whether it applies to enough planes to qualify for 2-A. But no one has changed this.
In fact, some direct counter-evidence:
"As for time, cause, and consequence, let's just say that the laws of the Dragon God do not apply to Oblivion. Oh, it's useful to adopt the trappings of duration when dealing with mortals, so you'll find Maelstrom quite familiar in that regard. We know how lost you feel away from the hand of Akatosh!"
Speaking of which, this should qualify all et'Ada for acausality when they are not controlling their aspects? We know from Vivec and several in-game instances that when an et'Ada's aspect (physical form) is destroyed, they return to a timeless state in which they can reform, as described:
"It is a bit like being at once awake and asleep. Awake, I am here with you, thinking and talking. Asleep, I am very, very busy. Perhaps for other gods, the completely immortal ones, it is only like that being asleep. Out of time. Me, I exist at once inside of time and outside of it."
"It's nice never being dead, too. When I die in the world of time, then I'm completely asleep. I'm very much aware that all I have to do is choose to wake. And I'm alive again. Many times I have very deliberately tried to wait patiently, a very long, long time before choosing to wake up. And no matter how long it feels like I wait, it always appears, when I wake up, that no time has passed at all. That is the god place. The place out of time, where everything is always happening, all at once."
