create timezone list in php symfony 4 code example

Example: symfony set timezone

If you can’t set it in php.ini, or you want to be sure the value is consistent independently of the target environment, the easiest way is to set it in your AppBundle:

class AppBundle extends Bundle
{
    public function boot()
    {
        parent::boot();
        date_default_timezone_set("Europe/Madrid");
    }
}
Alternatively, if you don’t have an AppBundle (or any other own bundle), you could add it to the AppKernel::registerBundles() method, right before the bundles are loaded.
