MongoDB validation schema:

bsonType: "object",
required: ["createdAt"],
properties: {
    createdAt: {
        bsonType: "date"
    }
}

Java class:

@Getter
@Setter
@NoArgsConstructor
@AllArgsConstructor
@MongoEntity(collection = "dogs")
public class Dog {
  private OffsetDateTime createdAt;
}

Java object creation:

var dog = new Dog();
dog.setCreatedAt(OffsetDateTime.now());

Insert document:

mongoDatabase.getCollection("dogs", Dog.class).insertOne(dog);

Retrieve document:

var dog = col.find().into(new ArrayList<>()).get(0);
System.out.println(dog.getCreatedAt()); //1970-01-20T21:13:08.290+01:00
System.out.println(OffsetDateTime.now()); //2024-04-29T12:58:10.168902949+02:00

In database the 1970 date is set.

Does MongoDB support OffsetDateTime? Is something missing to insert the date in correct format?
