1. A system utilizing precise time signals; said system comprising:
a timing input/output interface to receive a time signal and a pulse per second signal;
a local real time clock counter with sufficient range to represent an absolute time, wherein said local real time clock counter is initiated with the absolute time from the time signal and synchronized with the pulse per second signal; and
a high resolution counter running at a local system clock frequency, wherein said high resolution counter is synchronized with the pulse per second signal;
wherein output from said local real time clock counter and said high resolution counter are combined to normalize local system events in the absolute time.
