Good Gravy, I Hate Sliding Time-Scales

From this week's Avengers #1 (don't worry, no story spoilers here):

Superbowl XL was February, 2006. 

Which means Cap was revived after that.

Which means that Cap slept through the Cold War.
And Vietnam.
And Watergate.
And disco.
And that he wouldn't understand any of the references from Happy Days or That 70s Show.
Cap slept through Rodney King and O.J. Simpson.
He slept through Calvin and Hobbes.
He slept through 9/11.
He slept through Tupac and Biggie.
He slept through Star Trek and Star Trek: The Next Generation and Star Trek Deep Space Nine and Star Trek Voyager and Star Trek Enterprise.
He slept through Sean Connery and George Lazenby and Roger Moore And Timothy Dalton and Pierce Brosnan.
He slept through William Hartnell and Patrick Troughton and John Pertwee and Tom Baker and Peter Davidson and Colin Baker and Sylvester McCoy and Paul McGann and Christopher Eccleston. And Peter Cushing, too. He may have been unthawed for David Tennant's first season.

Why oh why do they have to tie these things to specific dates? 

P.S. This means the Avengers were formed in 2005 or 2006, giving you a starting date for the Fantastic Four of roughly 2003-2004. Which at least probably fits with the recent Marvel Two-In-One that showed Reed & Ben & Von Doom in college together in 1998...
