This is proof of work, I successfully patched date input controls on my old Safari. But it's not ready for use. As specified in the README of the polyfill project:
This screws up the produced dates completely, so it would be required to add the offset manually – but only for Safari. This means some extra work, but it's definitely doable. We can now recommend the DateValueAccessor to our readers without any restrictions, it will (soon) work in all browsers without any concerns.
