Detailed Description

The clock interface is the interface between the timer library and the platform specific clock functionality. The clock interface must be implemented for each platform that uses the timer library.

The clock interface does only one this: it measures time. The clock interface provides a macro, CLOCK_SECOND, which corresponds to one second of system time.
