Date timezone with Spring boot and Jackson

Question

I'm developing a spring boot application that handles dates. When I submit an Appointment object that has a startDateTime and an endDateTime (Both are of type java.util.Date) I send a format like this:

{
    "lastName": "Jhon",
    "firstName": "Doe",
    "email": "[email protected]",
    "description": "MyDescription",
    "startDateTime": "2017-10-09T22:43:07.109+0300",
    "endDateTime": "2017-10-09T21:40:07.109+0300",
}

When data is persisted in database it's with the correct timezone, when I try to retrieve my data back, they seem correct when I'm debugging however, once they are serialized by Jackson I have an output with these as value:

"startDateTime": "2017-10-09T19:43:07.109+0000",
"endDateTime": "2017-10-09T18:40:07.109+0000",

How can I configure Jackson to make usage of timezone that comes with the data from my repository?

------Update---------

I tried the answer with OffsetDateTime but the output is quite weird:

"startDateTime": {
        "offset": {
            "totalSeconds": 7200,
            "id": "+02:00",
            "rules": {
                "fixedOffset": true,
                "transitionRules": [],
                "transitions": []
            }
        },
        "month": "OCTOBER",
        "year": 2017,
        "hour": 21,
        "minute": 49,
        "nano": 654000000,
        "second": 15,
        "dayOfMonth": 9,
        "dayOfWeek": "MONDAY",
        "dayOfYear": 282,
        "monthValue": 10
    }

I would like to have something like:

2017-10-09T22:43:07.109+0300
