javascript - Weird Date Format Help -

i created extension method uses built-in asp.net serializer serialize objects json send server via ajax so:

namespace extensionmethods.json { public static class jsonhelper {     public static string tojson(this object obj)     {         javascriptserializer serializer = new javascriptserializer();         return serializer.serialize(obj);     }      public static string tojson(this object obj, int recursiondepth)     {         javascriptserializer serializer = new javascriptserializer();         serializer.recursionlimit = recursiondepth;         return serializer.serialize(obj);     } } }  //usage string json = myobject.tojson(); 

this works fine, except dates, sends dates in format:

/date(1291276800000)/ 

is there way fix serverside date comes more manageable, or have stupid character parsing on client side (ie, scrape digits out of parens , try set date using number milliseconds)? or there better way i'm overlooking? i've tried date.parse([the date]) errors out "invalid date format".

that valid json date. have @ other question date back. how format microsoft json date?
