It's possible to give feels to a time travel plot. Steins;Gate and Madoka are examples of that.

That said, Ozpin as a time traveller via semblance feels kinda OP, so I lean on the age theory than the time travel one as well.

Ozpin feels old. Even compared to Grampa Dust and Professor Port. Maybe he's using Dust to fuel his age, or some other method.

I'm gonna hold onto the idea that Ironwood and Qrow are at least still around his generation for now though.

Ironwood could also potentially be the Weiss to Ozpin's Ruby...

As for Cinder, she feels like she's at least a generation ahead of them, while being at least two generations behind RWBY. The livestream did say that she's young enough to pass for a student, but too old to be around RWBY's age.

I also personally think she has more connections with Summer rather than Ozpin. This goes to  my (slightly nutty) theory of From Summer to Fall, wherein Cinder was Summer's best student.
