[BUG] DateTime fields are always considered "dirty"

[lindseydiloreto]

Description

When you save an Entry, the DateTime fields are always considered "dirty", even if the DateTime value did not change.

Steps to reproduce

1. Create a DateTime field.
2. Create an Entry with that field.
3. Save the Entry with a normal DateTime value...

4. Add this event to your module...

Event::on(
    Entry::class,
    Entry::EVENT_AFTER_SAVE,
    function (ModelEvent $e) {
        /* @var Entry $entry */
        $entry = $e->sender;

        Craft::dd($entry->getDirtyFields());

    }
);

5. Resave the entry.
6. You'll notice that the DateTime fields are always considered "dirty", even if the value didn't change.
