I have one of the following date fields on my model:

@Schema(description = "Reg date")
private OffsetDateTime regDate;

I have GET method which returns my model and the dates with following format: "2022-11-01T11:11:11.715018+03.00"

But when I open my swagger (openApi) it represents the wrong format for default response for date fields: "2022-11-01T11:11:11.546Z".

When I add example to my field @Schema(description = "Reg date", example = "2022-11-01T11:11:11.715018+03.00") the swagger represent it as it is. But I have more than 100 of date fields and I dont want to add example for all of them. Is there any common solution for this?

From what I know, there are two main ways to enforce for all of your date fields this behavior:

- Use the @JsonFormat annotation to enforce the format in your model, something like this:

@Schema(description = "Reg date")
@JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd'T'HH:mm:ss.SSSXXX")
private OffsetDateTime regDate;

- You can also try to configure Jackson globally, as I assume you're running this in Spring Boot. If I am correct, read this article for how you can do so: https://www.baeldung/spring-boot-customize-jackson-objectmapper. By configuring Jackson globally, you can avoid the need of annotating each individual field.
