Typo3 : datetime +2 hour gap issue - typo3

Question

I have an extension to create events and I can set hours for the start and end of the event.
When I display my hours, there is a gap of +2 hour. When I set 10:00, it display 12:00 .
there is my debug :
I display it like that, and I found a temporary but ugly solution by adding "-2 hours" :
<div class="date mb-4 mb-md-0">
<f:format.date format="%d %B %Y">{atelier.date}</f:format.date>
<f:format.date format="H:i" base="{atelier.heuredebut}">-2 hours</f:format.date>
-
<f:format.date format="H:i" base="{atelier.heurefin}">-2 hours</f:format.date>
</div>
If it can help, there is my model :
protected $heuredebut;
/**
* #return \DateTime
*/
public function getHeuredebut()
{
return $this->heuredebut;
}
/**
* #param \DateTime $heuredebut
*/
public function setHeuredebut($heuredebut)
{
$this->heuredebut = $heuredebut;
}
and my TCA :
'heuredebut' => [
'exclude' => true,
'label' => 'LLL:EXT:reservationatelier/Resources/Private/Language/locallang_db.xlf:tx_reservationatelier_domain_model_atelier.heuredebut',
'config' => [
'type' => 'input',
'renderType' => 'inputDateTime',
'dbType' => 'time',
'eval' => 'time, int, null',
],
],
I checked my settings of my server and my php version, everything was ok.
So that's not the problem, do you have any idea where it could be?
thanks you

Answer 1

There's a configuration variable $GLOBALS[‘TYPO3_CONF_VARS’][‘SYS’][‘phpTimeZone’]. Start-/Stoptime are calculated based on this timezone.
For instances hosted/maintained in Germany it's $GLOBALS[‘TYPO3_CONF_VARS’][‘SYS’][‘phpTimeZone’] = 'Europe/Berlin' (winter: UTC/GMT +1, summer: UTC/GMT +2).
