Is there a single word for 'in keeping with the times'? [closed]

For example: 'The book is racist, in keeping with the time it was written.'

For its generation.

In Genesis it is said of Noah that he was a righteous man, blameless among the people of his time. This is a slightly modernized version of;

Noah was a righteous man, blameless in his generation.

The point made in the original text is that for that generation Noah had always done the right thing, unlike so many. The text is admitting that things change over time and people have to deal with the rules and context they find themselves in.

The only thing that can be considered as racist in any time is a text that dutifully explains why races [definition please] are different and one is (usually clearly) better than another. What people commonly refer to as racist texts are those that display a bias (perceived or otherwise) that is clear by modern lights but may not have been quite so when they were current, in their own generation
