User blog:HDMaster/How many years after Portal 1 does Portal 2 take place?

I've been wondering about this for a while, and from what I've seen, it's anywhere from 20 years - 50000 years. I think 200 years seems good, but the state of the relaxation chamber seems a bit good for 200 years. The same thing goes for paper and wood. And what about Chell's clothing? I'd like to hear what you think, and why, if you are a Portal fan.
