The moving time scale started way before, originally Stan Lee wanted the Marvel Universe's time to move as fast as our universe's time, but he realized if he wanted the Marvel Universe to last, he couldn't do that.

And it's just easy to understand. It's like a small little insignificant retcon every 4 years. Back in 2008, Secret Invasion took place in 2008, now in 2013 it took place in 2012.

And so it goes, more or less...
