Symfony3 Error manipulating time duration with doctrine - time

Question

I want to use a variable time as the amount of time passed to do something:
/**
* #var \DateTime
*
* #ORM\Column(name="TempsPasse", type="time", nullable=true)
*/
public $tempsPasse;
Code:
$Information->setTempsPasse(new \DateTime($Log->getTempsPasse()->format('H:i:s')));
$Information->setTempsPasse(clone($Log->getTempsPasse()));//Same result
$Information->setTempsPasse(new \DateTime('01:00:00'));//Same result
Where echo($Log->getTempsPasse()->format('H:i:s')); show: 01:00:00
Then when I flush I get this error:
FatalErrorException in TimeType.php line 53: Error: Call to a member
function format() on a non-object
Where am I wrong and how can I handle time with doctrine ?
EDIT
/**
* #var \DateTime
*
* #ORM\Column(name="TempsPasse", type="time")
*/
public $tempsPasse;
/**
* Set tempsPasse
*
* #param \DateTime $tempsPasse
*
* #return Log
*/
public function setTempsPasse($tempsPasse)
{
$this->tempsPasse = $tempsPasse;
return $this;
}
/**
* Get tempsPasse
*
* #return \DateTime
*/
public function getTempsPasse()
{
return $this->tempsPasse;
}
That's the same code for both entities.

Answer 1

I wonder if this works:
$Information->setTempsPasse( new \DateTime($Log->getTempsPasse()) );
The new \DateTime may be expecting a DateTime object...
Otherwise, can you edit your post and show how you create the $Log object first, and the code leading up to that.
The one thing I'm thinking is when you create the new \DateTime it is expecting line this:
new \DateTime( '01:00:00' )
Notice the quotes around the time parameter.
