Right, the birthday issue - I don't think it meshes with the rest of the golden age and tend to write it off as a mistake/misjudgement, rather than using it as a benchmark. What issue was it (I'm sure it it was 8 years after he appeared, that would be noted already). As for aging real time, I only meant for the first few years (that's the argument I saw), not the entire golden age.
As for referencing years ago events without characters aging - I give you this, from 1977:

Not really sure when they became unwilling to use real-time references, or even if this was just a one-off.
