match cryptojs with c# hmacsha512

Question

Why are my HMACs different?
I've created a visual studio 2012 solution here: https://github.com/tonyeung/hmacsha512

My js

    <script src="http://crypto-js.googlecode.com/svn/tags/3.1.2/build/components/enc-base64-min.js"></script>
    <script src="http://crypto-js.googlecode.com/svn/tags/3.1.2/build/rollups/hmac-sha512.js"></script>

    var rawSig = "abc:123:Fri, 28 Jun 2013 15:03:00 GMT";
    var token = "c22b31a2-780b-4ac5-8bd5-1296b05130f4"
    var hash = CryptoJS.HmacSHA512(rawSig, token);
    var sig = hash.toString(CryptoJS.enc.Base64);

my c#

    public JsonResult hmac(string sig, string token)
    {
        var signature = string.Empty;
        using (var hmac = new HMACSHA512(Encoding.UTF8.GetBytes(token)))
        {
            var hash = hmac.ComputeHash(Encoding.UTF8.GetBytes(sig));
            signature = Convert.ToBase64String(hash);
        }

        return Json(signature);
    }

the result:

I needed to flip the cryptojs reference

from

<script src="http://crypto-js.googlecode.com/svn/tags/3.1.2/build/components/enc-base64-min.js"></script>
<script src="http://crypto-js.googlecode.com/svn/tags/3.1.2/build/rollups/hmac-sha512.js"></script>

to

<script src="http://crypto-js.googlecode.com/svn/tags/3.1.2/build/rollups/hmac-sha512.js"></script>
<script src="http://crypto-js.googlecode.com/svn/tags/3.1.2/build/components/enc-base64-min.js"></script>
