Millennium Actress...kind of
. Not "real" time travel, but fictional time travel used to portray emotional realism...you know, just see it, it'll make sense afterwards...
Noein...kind of
. More dimensional travel to future versions of reality...
Zipang - completely and totally about what you would do if you traveled through time...
Now and Then, Here and There - they do travel through time in the first episode, but it is not the main focus of the series (think,
Inuyasha, only not a silly little kids story).
