Abstract
A system and method employing a precisely synchronized time in connection with a distributed hardware architecture are disclosed. Using an independent and trusted time signal and a second transition pulse signal, each resource in the distributed hardware architecture may be synchronized precisely to the same absolute time.
Claims7
A method of generating a local event timestamp having a precise time;
- said method comprising:
- clocking a local real time clock counter with sufficient range to represent an absolute time;
- employing a trusted time signal to load the local real time clock counter with the absolute time;
- employing a trusted pulse per second signal to synchronize a second transition of the local real time clock counter and to reset a high resolution counter running at a local system clock frequency;
- and
- generating a local event timestamp with a resolution of a local system clock period using the absolute time and a high resolution local offset responsive to said employing the pulse per second signal.
