As I said above, basically the entire lives of someone who exists in the modern age (who isn't there due to a prolonged lifespan, time travel, suspended animation etc.) are subject to the sliding timescale.

A perfect example is Reed Richards:

In he states that he fought in World War II (topical reference). That story was published in 1963. Whereas, published in 2006 depicts Reed Richards as a child in the 1950s during the McCarthy Hearings of Un-American Activities (also topical).

Reed was in his early 40s in the early days of the Fantastic Four and in his early 50s around the time of Civil War. If you were reading Fantastic Four #11 in 1963 it would make sense that Reed was fighting World War II 20 years earlier.

If you were reading the comics published in 2006, then it would make sense that Reed Richards could have been a child during the late 1950s (it's a bit of a stretch when you crunch the math about him being alive during the McCarthy trials, but it's not impossible.)

That last example I have is which shows a tombstone for Reed Richards on the front cover. It states his life was from 1961-2012. If that tombstone would be believed he was 51 around the time the story was published. If you were reading Fantastic Four #605 in 2012 that would make sense.

So yes there is... But only as it pertains to the every day lives of the characters who exist in the Modern Age.

I'd say that there is about 70-80 years of "Pre-Fantastic Four #1" that would be subject to the Sliding Timescale as well. The character histories move forward.

That's why you should never use any specific calendar dates while referring to someone's past life pre-Fantastic Four #1 unless there is a just reason for it (IE: they are a character rooted in the 1940s or 50s or 60s)

So always watch out for that.
