Deserializing json dates created by Sys.Serialization.JavaScriptSerializer.Serialize with DataContractJsonSerializer

I'm using the Sys.Serialization.JavaScriptSerializer client class to serialize an object to json and transfer it to a service where I deserialize it to an object using DataContractJsonSerializer.

 I've noticed that dates are serialized on the client without the time zone (extra 4 digits after the 13 digits of the ticks), thus making the DataContractJsonSerializer deserialize dates to UTC kind instead of Local kind.

 Is there a way to make the client javascript serializer serialize dates with the time zone ? not by changing the original embedded script code in the System.Web.Extensions ?

 (right now, to fix this, I use regular expressions to add my timezone to the date parts in the string on the server - I can allow myself to do this because the application is meant to run only in our country where there is one time zone)

Thanks,

Ido.
