How to customize Timestamp format?

Question

Java

There is an essence

import java.sql.Timestamp;

@Getter
@Setter
@ToString
@NoArgsConstructor
@AllArgsConstructor
@Entity
public class Car {

    @Id
    @GeneratedValue
    @JsonIgnore
    private Long id;

    @NotNull(message = "car number can't be null")
    @Pattern(regexp="[A-Z0-9\\- ]{4,16}", message = "invalid car number format")
    private String carNumber;

    private Timestamp timestamp;
}

Before saving which I put down a timestamp

@Override
    public Car saveCar(Car car) {
        car.setTimestamp(new Timestamp(System.currentTimeMillis()));
        return carRepository.save(car);
    }
