* The clock interface is the interface between the \ref timer "timer library"

|
* and the platform specific clock functionality. The clock

|
* interface must be implemented for each platform that uses the \ref

* timer "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.
