Regression: JsvSerializer.DeserializeFromString throws FormatException when deserializing DateTime in AR-SA culture

What steps will reproduce the problem?

With CurrentUICulture/CurrentCulture set to AR-SA, attempt to deserialize a 
DateTime that does not contain a fractional time.  Full repro example below.

using System;
using System.Globalization;
using System.Threading;

namespace ServiceStackDateBug
{
    public class Program
    {
        public static void Main(string[] args)
        {
            // This will work w/ all versions of ServiceStack.Text.dll.
            // Date will be serialized as 2011-02-07T09:02:03.001Z
            TestValues(1, 2, 3, 1);

            // This will only work w/ the oldest version.
            // Date will be serialized as 2011-02-07T01:02:03Z (no fractional time)
            TestValues(1, 2, 3, 0);
            Console.Read();
        }

        private static void TestValues(int hours, int minutes, int seconds, int millis)
        {
            Thread.CurrentThread.CurrentUICulture = new CultureInfo("en-us");
            Thread.CurrentThread.CurrentCulture = CultureInfo.CurrentUICulture;

            var test = new TestDto { Date = DateTime.Today.AddHours(hours).AddMinutes(minutes).AddSeconds(seconds).AddMilliseconds(millis) };
            Console.WriteLine("Test date: {0}", test.Date);

            var serializer = new ServiceStack.Text.Jsv.JsvSerializer<TestDto>();
            var serialized = serializer.SerializeToString(test);

            Console.WriteLine("Serialized value: {0}", serialized);

            Thread.CurrentThread.CurrentUICulture = new CultureInfo("ar-sa");
            Thread.CurrentThread.CurrentCulture = CultureInfo.CurrentUICulture;

            var deserializer = new ServiceStack.Text.Jsv.JsvSerializer<TestDto>();
            var deserialized = deserializer.DeserializeFromString(serialized);

            Console.WriteLine("Deserialized date (AR-SA): {0}", deserialized.Date);

            Console.WriteLine("Press any key to continue...");
            Console.Read();
            Console.WriteLine();
        }
    }

    public class TestDto
    {
        public DateTime Date { get; set; }
    }
}

What is the expected output? What do you see instead?

Expected: successful deserialization of the DateTime.

Actual: throws a FormatException, "The DateTime represented by the string is 
not supported in calendar System.Globalization.UmAlQuraCalendar."

What version of the product are you using? On what operating system?

ServiceStack.Text.dll v1.57

Please provide any additional information below.

This repros w/ v1.57 and v1.55, but does not repro w/ the older version of 
ServiceStack.Text.dll from March 2010.
