The GraphQL Content API’s DateTime scalars now returns the UTC offset (e.g. +02:00) provided from Content Management API, matching the behavior of the Content Delivery API (CDA).

Previously, GraphQL API would always return the DateTime scalars as an ISO 8601 Zulu time string, meaning a DateTime saved as "2021-04-19T09:10.000+02:00" would be returned by GraphQL API as "2021-04-19T07:10.000Z", whereas Content Delivery API would return the original UTC offset.

You can read more about the GraphQL Content API in our Developer docs.
