This disclosure relates to systems and methods for verification of time sources. In various embodiments, one or more secondary time sources may be used to verify the accuracy of a primary time source prior to relying on a time signal created by the primary time source. In one embodiment, a first interface is configured to receive the primary time signal from a primary time source, and a second interface in communication with a secondary time source is configured to receive a secondary time signal. A time assessment subsystem is configured to determine an occurrence of a verification criteria. Upon the occurrence of the verification criteria, the system may compare the primary time signal and the secondary time signal to determine whether that the primary time signal is consistent with the secondary time signal. If the signal is consistent, the primary time source may be utilized by the system.

Verification of time sources

The present application discloses monitoring a plurality of time inputs to detect a defined time event and providing a report of the plurality of time inputs for analysis in response to detecting the defined time event. To create the report, an event monitor records data relating to the plurality of time inputs in a temporary memory for a defined window of time. In response to detecting the defined time event, the event monitor transfers the data recorded in the temporary memory to a persistent memory and continues to record data relating to the plurality of time inputs to the persistent memory for a second defined window of time. The event monitor provides a report of the data relating to the plurality of time inputs stored in the persistent memory for analysis.

Synchronized clock event report

A system and method for customization of the settings configuration process for an intelligent electronics device is disclosed. The disclosed system and method permits the end user to customize not only the operation of an intelligent electronics device for a particular application, but also permits the end user to customize the process used to configure the settings of the device. A customized settings management user interface can be designed by an end user and can be used later during the settings configuration process for one or more intelligent electronics devices. Preferably, the customized settings management user interface will be tailored to meet application-specific objectives and to provide for a relatively more efficient settings configuration process.
