Automatically correctable clock

A time-keeping correction apparatus for correcting time of a slave time-keeper in accordance with a master time-keeper, comprising:

• an input port for receiving a master signal representative of a time correction from the master time-keeper;
• a selector for permitting a user to select a correction scheme from among a plurality of correction schemes;
• circuitry coupled with the input port and the selector for analyzing the master signal in accordance with the selected correction scheme and for developing a slave correction signal to be sent to the slave time-keeper, and
• an output coupled with the circuitry for sending the slave correction signal to the slave time-keeper.

A time-keeping correction apparatus for correcting time of a slave time-keeper in accordance with a master time-keeper, comprising:

• an input port for receiving a master signal representative of a time correction from the master time-keeper;
• correction software resident in the apparatus and including a code segment for representing a current position of hands of the slave time-keeper;
• circuitry coupled with the input port for analyzing the master signal and the code segment, for calculating a quantity of time to advance slave time-keeper time, for incrementing the quantity of the time to advance the slave time-keeper in order to adjust for a passage of time during a correction cycle, and for developing a slave correction signal representative of the quantity of time to be sent to the slave time-keeper;
• and
• an output coupled with the circuitry for sending the slave correction signal to the slave time-keeper.
