  /**********************
    This is the standard TypeConverter class used with TIME columns 
    in the Ndb Adapter.
  
    On the JavaScript side, this converter takes a string formatted as 
    "HH:MM:SS.sss" with optional sign +/-, and precision after the decimal
    point up to six digits.
    
    On the database side, TIME columns are read and written using a MySQLTime 
    structure.  MySQL TIME is a signed type, and the sign is preserved.  
    In MySQL 5.6, MySQL TIME can also support up to microsecond precision. 
  
    An application can override this converter and use MySQLTime directly:
      sessionFactory.registerTypeConverter("TIME", null);
    
    Or replace this converter with a custom one:
      sessionFactory.registerTypeConverter("TIME", myConverterClass);
