IsoDate.java

/* IsoDate utility class for kXML-RPC
 *
 * This class replaces org.kobjects.isodate.IsoDate that as previously used by 
 * kxmlrpc for encoding and decoding Date to/from ISO8601 format. Previously it 
 * incorrectly coded to full ISO8601 format, when the XML-RPC specification uses 
 * a ISO8601-style format (which is NOT ISO8601 compliant).
