in mysql to mysql connection datetime columns are replicated as string. Ex: '2018-02-09 094500' is replicated as '2018-02-09T064500.000000Z'. Is there a solution in airbyte for this?

@Doğacan Düğmeci thanks for this question, I added to our discourse: https://discuss.airbyte.io/t/source-mysql-datetime-column-is-replicated-with-microseconds/260/2

you mean then I have to transform back to datetime by myself?

This is a solution, you can export the normalization project and edit to your needs. Airbyte create normalization as more generic as possible.

sorry (that I'm not a software engineer) where and how should I edit exactly (on a docker deployment)?

Hey you can read more about them here https://docs.airbyte.com/operator-guides/transformation-and-normalization
