Component Types for Clocks

Apple has defined a type value and a number of subtype values for clock components. All clock components have a component type value of 'clok' . The component subtype value indicates the type of clock. You can use the following constants to specify these type and subtype values.

#define clockComponentType                   'clok'     /* clock component type */
#define systemTickClock                      'tick'     /* system tick clock */
#define systemSecondClock                    'seco'     /* system seconds clock */
#define systemMillisecondClock               'mill'     /* system millisecond clock */
#define systemMicrosecondClock               'micr'     /* system microsecond clock */
