Clock diagnostics

A clock comprising:

• a slave clock configured to be coupled to a master clock, and for receiving data from the master clock using a communication protocol;
• and
• means within the slave clock for determining and displaying at the slave clock the communication protocol currently in use by the slave clock.

A clock comprising:

• a slave clock configured to be coupled to a master clock, and for receiving data from the master clock using a communication protocol;
• and
• means within the slave clock for determining and displaying at the slave clock the amount of time that has passed since data was received by the slave clock from the master clock.

A clock comprising:

• an analog slave clock including display hands driven by at least one stepper motor coupled to the hands by gears, the slave clock further configured to be coupled to a master clock;
• and
• means within the slave clock for initiating and performing a diagnostic test to determine operability of the gears and motor upon activation of a control device, and to display results of the diagnostic test via a display device at the slave clock.

A master/slave clock system, comprising:

• a master clock coupled to at least one slave clock, the master clock located remotely from the at least one slave clock;
• and
• means within the master clock for initiating and performing semi-automatic diagnostic tests on current status and operability of components of the at least one slave clock upon activation of a control device at the master clock by an operator, and to display results of the diagnostic tests via a display device.

A clock adapted for use in a master/slave clock system and including means to perform semi-automatic diagnostic tests on slave clock components, comprising:

• at least one slave clock configured to be coupled to a remote master clock;
• a processing unit and a memory at the slave clock, the processing unit operating under software control, the processing unit configured to control slave clock functions;
• whereby the processing unit is further configured to initiate and perform diagnostic tests on current status and operability of components of the slave clock upon activation of a control device, and to display results of the diagnostic tests via a display device at the slave clock.

• whereby the processing unit is further configured to initiate and perform a diagnostic test to determine the operability of the memory upon activation of a control device, and to display a result of the diagnostic test via a display device at the slave clock.
