Synchronized Clock Event Report
First Claim
1. A method comprising:
- receiving a plurality of time inputs at a time distribution device;
monitoring the plurality of time inputs to detect a defined time event;
periodically recording data relating to the plurality of time inputs in a temporary memory, wherein the data relating to the plurality of time inputs is retained in the temporary memory for a first defined time; and
in response to detecting the defined time event;
transferring the data relating to the plurality of time inputs from the temporary memory to a persistent memory; and
continuing to periodically record data relating to the plurality of time inputs to the persistent memory for a second defined time.

Abstract
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.

8. A time distribution device for receiving and distributing a time signal, comprising:
-
a plurality of receivers, each configured to receive a time signal of a plurality of time signals; a temporary memory for periodically storing data relating to the plurality of time signals, wherein the temporary memory is configured to retain the data relating to the plurality of time signals for a first defined time; an event monitor for detecting a defined time event; and a persistent memory for storing the data from the temporary memory in response to the event detector detecting the defined event and periodically storing data relating to the plurality of time signals for a second defined time after detecting the defined time event. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A time distribution device for receiving and distributing a time signal, comprising:
-
a global navigational satellite system (GNSS) receiver suitable for receiving a GNSS signal and determining time information from the GNSS signal; an event monitor configured to collect data relating to the GNSS signal and detect a defined time event; a temporary memory for periodically storing the data relating to the GNSS signal, wherein the temporary memory is configured to retain the data relating to the GNSS signal for a first defined time; and a persistent memory for storing the data from the temporary memory in response to the event detector detecting the defined event and periodically storing data relating to the GNSS signal for a second defined time.
