First Claim
Patent Images
1. A computer program product to facilitate the providing of timing information to primary time servers of coordinated timing networks, the computer program product comprising:
- a storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method comprising;
obtaining by a primary time server of a coordinated timing network time code information from a secondary time server; and
employing by the primary time server the time code information from the secondary time server to provide time synchronization in the coordinated timing network, wherein the employing of the time code information from the secondary time server is in response to an indication that time code information of the primary time server is unavailable, and wherein the primary time server remains as current time server of the coordinated timing network, instead of having the secondary time server take over as the current time server.

Abstract
A primary time server of a Coordinated Timing Network remains as current time server, even if time code information of the primary time server is unavailable. The primary time server receives the necessary or desired timing information from a secondary time server and uses that information to maintain time synchronization within the Coordinated Timing Network.
