What remains is the set of - * comma-separated date components, which are also very - * easy to parse. - * - * The server should send this same format to the - * client, which can simply eval() it just as with the - * remainder of JSON. - * - * A requirement of the implementation of the server is - * that after a date has been sent from the client to - * the server, converted by the server into whatever - * native type the date will be stored or manipulated - * in, convered back to JSON, and received back at the - * client, a comparison of the sent and received Date - * object should yield identity.
