LocalDateTime is converted to OffsetDateTime in client

Question

This is my code to send to the client:

@DateTimeFormat(pattern = FormatConstants.DEFAULT_DATE_FORMAT)
private LocalDateTime finalizationDate;

when i generate client with swagger,apicodegen

it creates jar for our customer and that variable becomes this:

  @SerializedName("finalizationDate")

  private OffsetDateTime finalizationDate = null;

Why this can be? What can i do? Should i convert our variable to also offsetdatetime?
