Techniques for analyzing and verifying time in machine-based networks

A method of synchronizing time in a machine-based system, the method comprising:

• receiving time reference information for a first operational element included in the machine-based system, wherein the time reference information is associated with a time reference source to which the first operational element is currently locked;
• analyzing the time reference information against a known correct timing state for the first operational element, wherein the known correct timing state is associated with a proper time reference source for the first operational element that is different from the time reference source to which the first operational element is currently locked;
• determining that the first operational element is not properly synchronized based on the time reference information and the known correct timing state;
• and
• in response to determining that the first operational element is not properly synchronized, causing a fault indicator associated with the first operational element to be displayed on a machine that monitors a plurality of operational elements included in the machine-based system.

A system, comprising:

• a local time reference;
• a memory storing a time maintenance application;
• and
• one or more processors that are coupled to the memory and the local time reference, and when executing the time maintenance application, are configured to:
• receive time reference information for a first operational element included in the system, wherein the time reference information is associated with a time reference source to which the first operational element is currently locked;
• analyze the time reference information against a known correct timing state for the first operational element, wherein the known correct timing state is associated with a proper time reference source for the first operational element that is different from the time reference source to which the first operational element is currently locked;
• determine that the first operational element is not properly synchronized based on the time reference information and the known correct timing state;
• and
• in response to determining that the first operational element is not properly synchronized, cause a fault indicator associated with the first operational element to be displayed on a machine that monitors a plurality of operational elements included in the system.
