Deserializing into DateTime works on sim but not on device

Hi all,

I am pulling an object via JSON from a web service. Dates and times are in a format similar to this: "2014-03-07T17:00:00". I am using Json.NET to deserialize the object which stores the dates into DateTime objects, which works perfectly fine in the simulator - but when I run the code on the device, I get really bizarre DateTime objects. Here is some relevant code for consideration.

protected IList<T> GetList<T>(string action)
{
    try
    {
                string content = this.WebClient.DownloadString(this.WebApiServiceUri + action);
                Console.WriteLine("WebService content received: {0}", content);
                return JsonConvert.DeserializeObject<IList<T>>(content, this.JsonSerializerSettings);
    }
    catch (WebException ex)
    {
        throw new WebServiceException(ex);
    }
}

For JsonSerializerSettings I've tried...

    //var format = "yyyy-MM-ddTHH:mm:ss";
    var dateTimeConverter = new IsoDateTimeConverter { DateTimeFormat = "o" };

    this.JsonSerializerSettings = new JsonSerializerSettings()
    { 
            NullValueHandling = NullValueHandling.Ignore,
            Converters = new List<JsonConverter>() { dateTimeConverter }
    };

Like I said, it works fine on the simulator, but very wrong in the device. Not like timezone offset wrong, like dates into the year 5000. Any ideas would be greatly appreciated.
