摘要：
A time keeping system having a first time module operable to keep a first time, a second time module operable to keep a second time, and a display module operable to visually display a third time that corresponds to the second time. The system also includes a control module operatively coupled to the first time module and to the second time module. The control module detects a time difference between the first time and the second time and adjusts the second time to reduce the time difference.
