[Interest] "Proper" Date Locale support?

[Jason H]

I'm working with localization of dates. There is a standard JS API:
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toLocaleString#Using_options

But QML defines it's own Date:
http://doc.qt.io/qt-5/qml-qtqml-date.html

The difference being the MDN refers to an "options" object, and Qt uses a format string. With the update to a newer V8 engine, will we get the options behavior?
