The people who know that the owl flies off at night, after morning dawns.
いつの世も people only know that this occurs.

I find it difficult to follow the middle statement in terms of how to
interpret ...が知るのは、夜が明けて朝になってから。with a period. and what いつの世も is describing.

Along with what any of this has to to with knowing the future.

Thank you

question
reading-comprehension cleft-sentences
fragmented statement and いつの世も
> そんな梟が夜に飛び立ったのを人が知る **のは** 、夜が明けて朝になってから( **です** )。  
>  It is (only) after dawn breaks and morning comes that people (can) realize
> the owl has flied off at night.

This is a [cleft sentence](https://japanese.stackexchange.com/a/19208/5010)
where the ～から part is pulled out for emphasis. です at the end of the sentence
has been omitted. The original sentence is:

> 夜が明けて朝になってから、人はそんな梟が夜に飛び立ったのを知ります。  
>  People realize the owl has flied off at night (only) after dawn breaks and
> morning comes.

* * *

いつの世も means "in any age", "regardless of the era", etc. It's in the same vein
as [どの～も](https://japanese.stackexchange.com/q/30850/5010) grammar.

> いつの世も人は起こったことしか知ることができないのです。  
>  Regardless of the era, people can only know things that have (already)
> happened.
