"Reverse time" works for me.
"Immense hockey fan" doesn't work for me. Come to that, nor does "big hockey fan". I would generally just say I'm either a fan or a huge fan. Anything more than that would potentially be an obsessed fan!
However, some people, when they meet a celebrity or a sports player, might say "I'm your biggest fan". I admit that it's odd that we use "biggest" but not "big".
