Automatically Update Create/Modify Time

The ORM has native support to do this, however a custom implementation could be achieved by adding your own event subscribers to the pre-persist event.

Native Support

To use the built-in functionality you need to implement the CreateModifyInterface on your entity class:

/**
 * @Orm\Entity
 */
class SomeEntity implements CreateModifyInterface
{
    // ..
}

This will give you a create time and a last-modified time - these fields will be automatically set on the pre-persist event (not flush).

Custom Implementation

If you wanted to build your own implementation or automatic field setters, you can do this by registering an event listener or subscriber to the Event::PRE_PERSIST event.

$entity_manager->getDispatcher()->addListener(Event::PRE_PERSIST, function(PersistEvent $event) {
    $entity = $event->getEntity();
    // Manipulate entity here
});

You may prefer to use subscribers instead of listeners for a more pure OO approach. See the CreateModifySubscriber class for an example implementation.
