has time travel. a bit old school as well. has a movie as well. they also did both in eng dub if you want that.
Suzumiya Haruhi no Yuuutsu had time travel and repeating days. Its the second season of the The Melancholy of Haruhi Suzumiya.
Miyazaki's "Spirited Away." Not really a time travel as such but in that theme. It won Best animated Feature, National Board of review, Winner Golden Bear Award the 52nd Berlin International Film Festival as well as Best Animated Film, New York Film Critic Circle. Bottom line, I liked it.
