Claim Text:
1. A method comprising: receiving, at a time distribution device, two or more consecutive time signals from a first external time source; determining a first duration between each of the two or more consecutive time signals from the first external time source, wherein the first duration is based on an internal oscillator; receiving, at the time distribution device, two or more consecutive time signals from a second external time source; determining a second duration between each of the two or more consecutive time signals from the second external time source, wherein the second duration is based on the internal oscillator; comparing the first duration and the second duration to determine a time source with the lowest variation in the duration between the two or more consecutive time signals; selecting the time source with the lowest variation as a best available time source; and distributing the best available time source to one or more consuming devices.
