You can implement it as a trait as well - like this:

createdAt ?? new DateTime();
    }

    /**
     * @param DateTimeInterface $createdAt
     * @return $this
     */
    public function setCreatedAt(DateTimeInterface $createdAt): self
    {
        $this->createdAt = $createdAt;

        return $this;
    }

    /**
     * @return DateTimeInterface|null
     */
    public function getUpdatedAt(): ?DateTimeInterface
    {
        return $this->updatedAt ?? new DateTime();
    }

    /**
     * @param DateTimeInterface $updatedAt
     * @return $this
     */
    public function setUpdatedAt(DateTimeInterface $updatedAt): self
    {
        $this->updatedAt = $updatedAt;

        return $this;
    }

    /**
     * @ORM\PrePersist()
     * @ORM\PreUpdate()
     */
    public function updateTimestamps(): void
    {
        $now = new DateTime();
        $this->setUpdatedAt($now);
        if ($this->getId() === null) {
            $this->setCreatedAt($now);
        }
    }
}

Add this trait to your entity (and don't forget @ORM\HasLifecycleCallbacks() notation):
