1) Are You Afraid of the Dark?
While this show was technically about teenagers telling scary stories around a camp fire, there were a number of those that dealt with time travel. The one I'm thinking of is when a student finds a necklace in her locker, she's able to travel back in time and see an explosion that killed the fellow student who was wearing it nearly 30 years before.
This anime is about a girl who falls through a well and transports herself back to feudal era Japan. It's kind of ridiculous but it's my favorite anime.
Fry is a pizza delivery man who ends up frozen in 1999 and wakes up in 2999. This show was always stupid fun.
