You could also adjust json2.js a bit to always use its own Date.prototype.toJSON instead of a possible native one. Here I uncommented two lines and it works correctly:

// if (typeof Date.prototype.toJSON !== 'function') {

    Date.prototype.toJSON = function (key) {

        return isFinite(this.valueOf()) ?
               this.getUTCFullYear()   + '-' +
             f(this.getUTCMonth() + 1) + '-' +
             f(this.getUTCDate())      + 'T' +
             f(this.getUTCHours())     + ':' +
             f(this.getUTCMinutes())   + ':' +
             f(this.getUTCSeconds())   + 'Z' : null;
    };

    String.prototype.toJSON =
    Number.prototype.toJSON =
    Boolean.prototype.toJSON = function (key) {
        return this.valueOf();
    };
// }
