using WCF serialized dates in JavaScript

gistfile1.js

String.prototype.DateWCF = function () {
    var d = new Date(parseInt(this.substr(6)));
    return (d.getUTCMonth() + 1) + '/' + d.getUTCDate();
};

//usage

var option = //some shipping option object returned from a RESTful WCF service
option.DeliveryEnd.DateWCF()

This example returns just the month and day, but you could certainly expand on that for your needs
