Answer 1

I came across a similar problem, but with a time field, and this question and @romanb 's answer helped.

I was getting the following error, much like the one in the question.

Call to a member function format() on a non-object in 
... /vendor/doctrine/dbal/lib/Doctrine/DBAL/Types/TimeType.php on line 50

The solution was similar, for fields of the time datatype, Doctrine will accept an instance of PHP's DateInterval

$quizFixture1->setCompletionTime(\DateInterval::createFromDateString('743 seconds'));
