After many years of not watching anime, I saw this and it restored my love of the medium. I asked /a/ for recommendations on "anime about time travel" and they told me "Madoka, and go to /wsr/"

So I watched Madoka (enjoyed it) and came here. Got anything else for me that's high quality anime about time travel?

I'm a complete outsider to anime so aside from the two I named and Disappearance of Haruhi, if you name a (time travel) show it's almost certain I have not seen it.
