DATE TIME with json format API - json

Question

sorry for my poor english btw , it's not my mother's tongue .
So i created an API using FOSRestBundle on syfmony 3 :
This one :
public function getHoraireAction(){
$Horaire = $this->getDoctrine()->getRepository('CBMedBundle:Horaire')- >findAll();
if(!$Horaire){
throw $this->createNotFoundException();
}
return $Horaire;
}
Entity Horaire.php with JMSSerializer
<?php
namespace CBMedBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use JMS\Serializer\Annotation\ExclusionPolicy;
use JMS\Serializer\Annotation\Expose;
use JMS\Serializer\Annotation\Groups;
use JMS\Serializer\Annotation\VirtualProperty;
/**
* Horaire
*
* #ORM\Table(name="horaire")
* #ORM\Entity(repositoryClass="CBMedBundle\Repository\HoraireRepository")
*
* #ExclusionPolicy("all")
*/
class Horaire
{
/**
* #var int
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var time
*
* #ORM\Column(name="Debut", type="time", length=10)
* #Expose
*/
private $debut;
/**
* #var time
*
* #ORM\Column(name="EntreeSalle", type="time", length=10)
* #Expose
*/
private $entreeSalle;
/**
* #var time
*
* #ORM\Column(name="HeureAnesthesie", type="time", length=10)
* #Expose
*/
private $heureAnesthesie;
/**
* #var time
*
* #ORM\Column(name="Operation", type="time", length=10)
* #Expose
*/
private $operation;
/**
* #var time
*
* #ORM\Column(name="incision", type="time", length=10)
* #Expose
*/
private $incision;
/**
* #var time
*
* #ORM\Column(name="finOpe", type="time", length=10)
* #Expose
*/
private $finOpe;
/**
* #var time
*
* #ORM\Column(name="Reveil", type="time", length=10)
* #Expose
*/
private $reveil;
/**
* #var time
*
* #ORM\Column(name="Sortie", type="time", length=10)
* #Expose
*/
private $sortie;
/**
* #ORM\OneToOne(targetEntity="CBMedBundle\Entity\Interventions", cascade= {"persist"})
* #Expose
*/
private $Interventions;
etc..
Everything is working , but it seems that the API do not return the true value of fields who have "time" type .
Horaire.php date time datas on mysql
And this is what i get when i test the API (using post man)
Error with Date time
How to fix that please .
Thanks

Answer 1

Ok i have found the solution .
i had to add these lines :
use JMS\Serializer\Annotation\Type;
//.....
/**
* #var time
*
* #ORM\Column(name="Debut", type="time", length=10)
* #Type("DateTime<'h-m-s'>")
* #Expose
*/
private $debut;
etc..
