Method and system for synchronizing multiple secure clocks using an average adjusted time of the secure clocks if the average adjusted time is within the limit intersection and using a substitute average adjusted time if the averaged adjusted time is outside the limit intersection
Method and system for synchronizing multiple secure clocks using an average adjusted time of the secure clocks if the average adjusted time is within the limit intersection and using a substitute average adjusted time if the averaged adjusted time is outside the limit intersection
A method for synchronizing secure clocks in a system without using any external clock, a system configured to perform the method, and a computer medium storing system code. Each secure clock is adjustable subject to a set of predetermined adjustment constraints. The intersection of the adjustment constraints of all the clocks is a limit intersection. The clocks may be synchronized to an average adjusted time of the secure clocks (if the average adjusted time is within the limit intersection) or to a substitute average adjusted time within the limit intersection if the average adjusted time is outside the limit intersection. Synchronization can occur in response to a request to adjust at least one of the clocks by a proposed clock adjustment value or to synchronize at least one of them without otherwise adjusting them.
