Jackson ObjectMapper adjusts dates to context timezone when deserializing even if explicitly disabled

This is the format of the date in JSON that I want to serialize/deserialize:

"2014-06-18T06:26:56-07:00"

The Joda DateTime field is declared as follows:

  @JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd'T'HH:mm:ssZ")
    private DateTime dueTime;

The mapper:

ObjectMapper mapper = new ObjectMapper().enable(SerializationFeature.INDENT_OUTPUT)
            .registerModule(new JodaModule())
            .disable(DeserializationFeature.ADJUST_DATES_TO_CONTEXT_TIME_ZONE);

mapper.writeValueAsString(objectWithDT)).as("application/json")

In the resulting JSON the date with timezone above changes to:

2014-06-18T13:26:56+0000

DeserializationFeature.ADJUST_DATES_TO_CONTEXT_TIME_ZONE is a deserialization feature and it's not taken into consideration when performing serialization.

One possible solution is to create an ObjectMapper instance with a TimeZone:

ObjectMapper mapper =  new ObjectMapper()
            .enable(SerializationFeature.INDENT_OUTPUT)
            .disable(DeserializationFeature.ADJUST_DATES_TO_CONTEXT_TIME_ZONE)
            .registerModule(new JodaModule())
            .setTimeZone(TimeZone.getTimeZone("GMT-7"));

For more details, check the DateTimeSerializer code.
