I came across an issue with daylight saving timezones where the day which changes the time is handled as a invalid date in PHP.

Since my form had a DateType field, I managed to fix this issue by setting both model_timezone and view_timezone to UTC. The same issue happened on a DateTimeType field, but setting the options didn't solve the error.

Looking further at the code, I realized that there's specific options been passed to the new DateType field created, and the timezone options aren't. This is the specific piece of code: https://github.com/symfony/symfony/blob/2.6/src/Symfony/Component/Form/Extension/Core/Type/DateTimeType.php#L113

Adding model_timezone and view_timezone to this array solved my problem.

Am I missing something here, or this options should be passed to the DateType field?
