I'm using React Widgets[0] and I prefer moment over Globalize (been through so much pain with this). Maybe it's time to either write a localizer for Luxor or find a new date time picker
[0] Current user's current locale is easy. If for some reason you need to show some other locale than what the browser is using you'll likely still need Moment or Globalize.
