Wrong time recording

I have these 3 classes as a template.

Object:

import java.io.Serializable;
import java.util.List;

import javax.persistence.CascadeType;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Inheritance;
import javax.persistence.InheritanceType;
import javax.persistence.OneToMany;
import javax.persistence.Table;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

import lombok.AllArgsConstructor;
import lombok.EqualsAndHashCode;
import lombok.Getter;
import lombok.NoArgsConstructor;
import lombok.Setter;

@AllArgsConstructor
@NoArgsConstructor
@EqualsAndHashCode
@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
@Entity
@Table(name="objeto")
@Inheritance(strategy=InheritanceType.JOINED)
public class Objeto implements Serializable{

    private static final long serialVersionUID = 1L;

    @Getter
    @Setter
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Getter
    @Setter
    @XmlElement
    @Column(nullable = false, length = 13, unique = true)
    private String numero;

    @Getter
    @Setter
    @XmlElement
    @Column
    private String sigla;

    @Getter
    @Setter
    @XmlElement
    @Column
    private String nome;

    @Getter
    @Setter
    @XmlElement
    @Column
    private String categoria;

    @Getter
    @Setter
    @XmlElement(name = "evento")
    @OneToMany(mappedBy = "objeto", cascade = CascadeType.ALL, fetch = FetchType.EAGER)
    private List<Evento> eventos;

    @Getter
    @Setter
    @XmlElement
    @Column
    private String erro;

}

Event:

import java.io.Serializable;
import java.time.LocalDate;
import java.time.LocalTime;

import javax.persistence.CascadeType;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
import javax.persistence.OneToOne;
import javax.persistence.Table;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
import javax.xml.bind.annotation.XmlTransient;

import lombok.EqualsAndHashCode;
import lombok.Getter;
import lombok.NoArgsConstructor;
import lombok.Setter;

@EqualsAndHashCode
@NoArgsConstructor
@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
@Entity
@Table(name = "evento")
public class Evento implements Serializable{

    private static final long serialVersionUID = 1L;

    @Getter
    @Setter
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Getter
    @Setter
    @XmlElement
    @Column
    private String tipo;

    @Getter
    @Setter
    @XmlElement
    @Column
    private Integer status;

    @Getter
    @Setter
    @XmlTransient
    @Column
    private LocalDate data;

    @Getter
    @Setter
    @XmlElement(name="data")
    private String dataAux;

    @Getter
    @Setter
    @XmlTransient
    @Column
    private LocalTime hora;

    @Getter
    @Setter
    @XmlElement(name="hora")
    private String horaAux;

    @Getter
    @Setter
    @XmlElement
    @Column
    private String descricao;

    @Getter
    @Setter
    @XmlElement
    @Column
    private String recebedor;

    @Getter
    @Setter
    @XmlElement
    @Column
    private String documento;

    @Getter
    @Setter
    @XmlElement
    @Column
    private String comentario;

    @Getter
    @Setter
    @XmlElement
    @Column
    private String local;

    @Getter
    @Setter
    @XmlElement
    @Column
    private Integer codigo;

    @Getter
    @Setter
    @XmlElement
    @Column
    private String cidade;

    @Getter
    @Setter
    @XmlElement
    @Column
    private String uf;

    @Getter
    @Setter
    @XmlElement
    @OneToOne(mappedBy="evento",cascade = CascadeType.ALL)
    private Destino destino;

    @Getter
    @Setter
    @ManyToOne(cascade=CascadeType.ALL)
    @JoinColumn(name = "objeto_id", referencedColumnName = "id")
    private Objeto objeto;

}

And Destination:

import java.io.Serializable;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.OneToOne;
import javax.persistence.Table;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

import lombok.AllArgsConstructor;
import lombok.EqualsAndHashCode;
import lombok.Getter;
import lombok.NoArgsConstructor;
import lombok.Setter;

@AllArgsConstructor
@EqualsAndHashCode
@NoArgsConstructor
@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
@Entity
@Table(name = "destino")
public class Destino implements Serializable{

    private static final long serialVersionUID = 1L;

    @Getter
    @Setter
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Getter
    @Setter
    @XmlElement
    @Column
    private String local;

    @Getter
    @Setter
    @XmlElement
    @Column
    private Integer codigo;

    @Getter
    @Setter
    @XmlElement
    @Column
    private String cidade;

    @Getter
    @Setter
    @XmlElement
    @Column
    private String uf;

    @Getter
    @Setter
    @OneToOne
    @JoinColumn(name = "evento_id")
    private Evento evento;

}

In the Event class I have the hour attribute which is a LocalTime , I fill in this field through this method:

public static LocalTime stringToTime(String src) {
        final DateTimeFormatter fHora = DateTimeFormatter.ofPattern("HH:mm");
        final LocalTime hora = LocalTime.parse(src, fHora);
        return hora;
    }

Let's say you have the time 12:00 .

My persistence class:

public class ServiceBase {

    @PersistenceContext(unitName = "tracker")
    protected EntityManager em;

public void insert(Objeto objeto) {
        this.em.persist(objeto);
    }

}

Until then, it's OK, when it's written to the bank mysql the value that is 12:00 writes as 15:00 as if GMT was 00:00 and ours is -03: 00. Does anyone know what's causing it and how can I resolve it?
