    Defaults in GetDateMessage options are, in general, NOT honored. Defaults are not serialized out-of-JVM, and the router does not recognize defaults in-JVM. Client side must promote defaults to the primary map.
    
    Parameters:
    
    version - the client's version String to be sent to the router; may be null; must be non-null if options is non-null and non-empty.
    
    options - Client options to be sent to the router; primarily for authentication; may be null; keys and values 255 bytes (not chars) max each
    
    Since:
