Symfony2 datetime best way to store timestamps?

Question

I don\'t know which is the best way to store a timestamp in the database. I want to store the entire date with hours minutes and seconds but it only stores the date ( for in

Answer 1

Building on @Pratt's answer I did this. I have 2 fields in my entities one for created and one for modified.

/**
* @ORM\Column(type="datetime")
 */
protected $created_at;

/**
* @ORM\Column(type="datetime")
 */
protected $modified_at;

And then using annotation I call this on prePersist and preUpdate

/**
 * @ORM\PrePersist
 * @ORM\PreUpdate
 */
public function updatedTimestamps()
{
    $this->setModifiedAt(new \DateTime(date('Y-m-d H:i:s')));

    if($this->getCreatedAt() == null)
    {
        $this->setCreatedAt(new \DateTime(date('Y-m-d H:i:s')));
    }
}

The function could be broken up into 2 functions one for create one for update, but this is working so I see no reason for the extra code when this is working properly.
