The Timekeeper is now closed, but once in the early am we saw him outside in this area. We also saw him in AK - on the way to Camp Minnie/Mickey from Discovery Island (coming from Dinoland direction). Right next to him was Chip/Dale. A good time to catch characters in AK is during the EMH.
We also saw him somewhere esle in AK, but I don't recall exactly where it was - only that I was surprised to see him at two places in the same park.
