protected java.lang.StringdateToString(int[] date)
Converts year object representation to String

param
date year object
return
lexical representation of month: CCYY with optional time zone sign

        StringBuffer message = new StringBuffer(5);
        append(message, date[CY], 4);
        append(message, (char)date[utc], 0);
        return message.toString();
public java.lang.ObjectgetActualValue(java.lang.String content, com.sun.org.apache.xerces.internal.impl.dv.ValidationContext context)
Convert a string to a compiled form

param
content The lexical representation of time
return
a valid and normalized time object

        try{
