Just came up on this question because we also started using knockout.js on our MVC3 app. Since we already have jQuery datepicker and we need to format dates differently by locale (portal has different languages and different formats are presented per language), so maybe this mashup of technological requirements arise somewhere else and will be useful:

var jsDateFormat = "@CultureHelper.JsDateFormat"; // can be something like yy-mm-dd

//...

 ko.bindingHandlers.date = {
    init: function (element, valueAccessor, allBindingsAccessor, viewModel) {
        var value = valueAccessor();
        if (value != null) {
            var jsonDate = new Date(parseInt(valueAccessor().substr(6)));
            element.innerHTML = jQuery.datepicker.formatDate(jsDateFormat, jsonDate);
        }
    },
    update: function (element, valueAccessor, allBindingsAccessor, viewModel) {
    }
};

And in the view then for example:

Date:
