First time travel: 20 Dec 1974
From his early days, Kermit brought news reports to Sesame Street. I don't know when he first reported from back in history, so I’ll arbitrarily say that the first one was his interview of Christopher Columbus in Episode 700 shortly before Christmas in 1974.
In the 35th anniversary special, “The Street We Live On,” Grover takes Elmo on a trip through time to see how the street was in the past. Also, in a PBS special, “Elmo Saves Christmas,” the red guy visits a future Christmas.
Columbus: But, say, what time is it?
Kermit: Oh, it’s about, ah, 1492.
No Time Travel. Move along.
