The ability to time travel through Jefferson's hat should be added to the Hat's ability. I would also like to add that the laws of magic that applies to the realm or the once upon a time verse isn't necessarily applied to the hat, for instance, the hat has rules with how many goes in must also come back regardless of how powerful the user is, so I guess the time travel ability is unique to the hat so long as you have magic to activate it, it has its own rules that transcends the laws of magic. This is just a big maybe.
